From 53109e0c403d53f51cfae9c3ecaad2c31bb460b1 Mon Sep 17 00:00:00 2001 From: janipauwels-sys Date: Mon, 28 Sep 2026 16:57:44 +0100 Subject: [PATCH 01/38] test: add security and stability test suites for issues 256-258 (#365) * test(api): add tests for upload content-type and size validation Adds tests to verify upload_signature validates content-type against an allowlist (image/png, image/jpeg, image/webp), rejects SVG (XSS vector), and enforces a maximum file size before forwarding to Cloudinary. Tests: - upload_signature_rejects_svg_content_type - upload_signature_rejects_oversized_body - upload_signature_accepts_a_valid_png Closes #256 * test(api): add tests for payment-status PII stripping Adds tests to verify get_payment_status (public, unauthenticated endpoint) does not leak payer_name or payer_email, while list_payment_link_payments (owner-facing, authenticated endpoint) still includes these details. Tests: - get_payment_status_response_does_not_include_payer_email_or_name - get_payment_status_still_returns_the_fields_a_payer_needs - list_payment_link_payments_owner_view_still_includes_payer_details Closes #255 * test(api): add tests for audit-log search term length cap Adds tests to verify list_audit_logs rejects oversized search terms before they trigger unindexed ILIKE scans in the database. Length cap is proposed at 100 characters. Tests: - list_audit_logs_rejects_search_term_over_the_length_cap - list_audit_logs_accepts_a_normal_length_search_term Closes #257 * test(store): add tests for address derivation error distinction Adds tests to verify allocate_address distinguishes between a derivation failure (from the muxed_address_for closure) and a genuinely missing wallet. Derivation failures should return a new AddressDerivationFailed variant, not the misleading NotFound. Tests: - allocate_address_returns_derivation_failed_not_not_found_on_a_bad_closure_result - allocate_address_still_returns_not_found_for_a_genuinely_missing_wallet Closes #258 --- .../tests/address_derivation_error_tests.rs | 97 +++++++++++++++ crates/api/tests/audit_log_search_tests.rs | 95 ++++++++++++++ crates/api/tests/payment_pii_tests.rs | 116 ++++++++++++++++++ crates/api/tests/upload_validation_tests.rs | 104 ++++++++++++++++ 4 files changed, 412 insertions(+) create mode 100644 crates/api/tests/address_derivation_error_tests.rs create mode 100644 crates/api/tests/audit_log_search_tests.rs create mode 100644 crates/api/tests/payment_pii_tests.rs create mode 100644 crates/api/tests/upload_validation_tests.rs diff --git a/crates/api/tests/address_derivation_error_tests.rs b/crates/api/tests/address_derivation_error_tests.rs new file mode 100644 index 0000000..ed3357b --- /dev/null +++ b/crates/api/tests/address_derivation_error_tests.rs @@ -0,0 +1,97 @@ +//!

The previous `date_trunc('day', now() AT TIME ZONE 'UTC')` yields a naive timestamp that Postgres re-interprets in the session TimeZone, so a non-UTC session shifted the budget day. - Withdrawal history (#259): add migration 0021 with a partial unique index on (wallet_id, stellar_tx_hash) for withdrawals (deduping any existing rows first), and make record_withdrawal_transaction idempotent (Ok(None) on conflict), upgrading a prior `failed` row to `confirmed` but never downgrading. - Ingest fan-out (#260): add list_wallets_page and wallets_due_for_poll_page (keyset on id, same backoff filter); the supervisor now iterates pages of 500 with backpressure instead of materialising every due wallet at once. - Allowlist (#262): the route already validates via to_base_account; document on Store::add_whitelisted_address that format validation is the caller's responsibility. --- crates/api/src/routes/submit.rs | 10 +- crates/ingest/src/lib.rs | 154 ++++++++++++------ .../0021_dedupe_withdrawal_transactions.sql | 21 +++ crates/store/src/lib.rs | 150 +++++++++++++---- crates/store/tests/store_tests.rs | 2 +- 5 files changed, 250 insertions(+), 87 deletions(-) create mode 100644 crates/store/migrations/0021_dedupe_withdrawal_transactions.sql diff --git a/crates/api/src/routes/submit.rs b/crates/api/src/routes/submit.rs index 69d5adf..2144d22 100644 --- a/crates/api/src/routes/submit.rs +++ b/crates/api/src/routes/submit.rs @@ -143,9 +143,10 @@ pub async fn relay_signed_transaction( ), }; - // Record outbound payments in the history the dashboard lists (best-effort). + // Record outbound payments in the history the dashboard lists (best-effort).

Connection errors, timeouts and 5xx are retried; other non-2xx are not. - webhooks: record the HTTP status and a response-body snippet (streamed, capped at 1 KiB, signature/secret redacted) on every delivery. New migration 0021 adds webhook_deliveries.response_body_snippet with a DB-level size CHECK. - api: expose response_body_snippet on the deliveries endpoint, and honour the validated ?limit= (it was hardcoded to 50). - webhooks: is_safe_url now classifies the WHATWG-normalised host with std::net, unwrapping IPv4-mapped IPv6 via to_ipv4_mapped() and rejecting the unspecified address. Closes the [::ffff:7f00:1] bypass and numeric shorthands like 0, 2130706433 and 0x7f.1. - ingest: to_stroops already rejects more than 7 fractional digits (it never truncated). Pin that with tests and log a warning when a record is skipped for an unparseable amount instead of dropping it silently. --- Cargo.lock | 2 + crates/api/src/routes/webhooks.rs | 7 +- crates/api/tests/api_tests.rs | 42 ++ crates/ingest/src/amount.rs | 24 + crates/ingest/src/lib.rs | 6 + ...0021_webhook_delivery_response_snippet.sql | 6 + crates/store/src/lib.rs | 7 +- crates/store/src/models.rs | 2 + crates/webhooks/Cargo.toml | 2 + crates/webhooks/src/lib.rs | 435 +++++++++++------- crates/webhooks/tests/dispatch_tests.rs | 195 ++++++++ docs/api.md | 8 +- 12 files changed, 560 insertions(+), 176 deletions(-) create mode 100644 crates/store/migrations/0021_webhook_delivery_response_snippet.sql create mode 100644 crates/webhooks/tests/dispatch_tests.rs diff --git a/Cargo.lock b/Cargo.lock index be45e62..e88c3c7 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1883,8 +1883,10 @@ version = "0.1.0" dependencies = [ "axum", "chrono", + "dotenvy", "hex", "hmac", + "octo-resilience", "octo-store", "reqwest", "serde", diff --git a/crates/api/src/routes/webhooks.rs b/crates/api/src/routes/webhooks.rs index 7d9ec34..acaaa41 100644 --- a/crates/api/src/routes/webhooks.rs +++ b/crates/api/src/routes/webhooks.rs @@ -91,6 +91,8 @@ pub struct WebhookDeliveryView { pub status: String, pub attempts: i32, pub response_code: Option, + /// First ≤ 1 KiB of the endpoint's last response body, for self-service diagnosis. + pub response_body_snippet: Option, pub created_at: chrono::DateTime, pub updated_at: chrono::DateTime, } @@ -174,10 +176,10 @@ pub async fn list_deliveries( return Err(ApiError::NotFound); } - // Retrieve deliveries (limit to last 50). + // Honour the validated `?limit=` (previously ignored in favour of a hardcoded 50). let deliveries = state .store() - .list_webhook_deliveries(endpoint_id, 50) + .list_webhook_deliveries(endpoint_id, limit) .await?; let views: Vec = deliveries @@ -190,6 +192,7 @@ pub async fn list_deliveries( status: d.status, attempts: d.attempts, response_code: d.response_code, + response_body_snippet: d.response_body_snippet, created_at: d.created_at, updated_at: d.updated_at, }) diff --git a/crates/api/tests/api_tests.rs b/crates/api/tests/api_tests.rs index 445d88d..b7c49bb 100644 --- a/crates/api/tests/api_tests.rs +++ b/crates/api/tests/api_tests.rs @@ -2643,3 +2643,45 @@ async fn submit_payment_validates_against_the_intents_own_address() { "a USDC payment to this intent's own address must pass validation and be relayed" ); } + +#[tokio::test] +async fn list_deliveries_response_includes_the_new_diagnostic_fields() { + let Some(state) = test_state().await else { + eprintln!("SKIPPED: set DATABASE_URL to run integration tests"); + return; + }; + let app = build_router(state.clone()); + let token = auth_token(&app, &state).await; + let wallet_id: uuid::Uuid = create_wallet_for(&app, &token).await.parse().unwrap(); + + // Seed a failed delivery directly: this test covers the read path, not dispatch. + let ep = state + .store() + .create_webhook_endpoint(wallet_id, "https://merchant.example/hook", "s") + .await + .unwrap(); + for _ in 0..2 { + state + .store() + .log_webhook_delivery( + ep.id, + "deposit.created", + &serde_json::json!({}), + "failed", + 3, + Some(503), + Some("upstream unavailable"), + ) + .await + .unwrap(); + } + + let uri = format!("/v1/wallets/{wallet_id}/webhooks/{}/deliveries?limit=1", ep.id); + let resp = app.oneshot(get_auth(&uri, &token)).await.unwrap(); + assert_eq!(resp.status(), StatusCode::OK); + let rows = body_json(resp).await["data"].as_array().unwrap().clone(); + assert_eq!(rows.len(), 1, "?limit= must be honoured"); + assert_eq!(rows[0]["response_code"], 503); + assert_eq!(rows[0]["response_body_snippet"], "upstream unavailable"); + assert_eq!(rows[0]["attempts"], 3); +} diff --git a/crates/ingest/src/amount.rs b/crates/ingest/src/amount.rs index 6fbea84..d22c9e8 100644 --- a/crates/ingest/src/amount.rs +++ b/crates/ingest/src/amount.rs @@ -9,6 +9,9 @@ const DECIMALS: usize = 7; /// Parse a Stellar decimal amount string into stroops.

(#268) - ingest: operation_index_from_toid decodes Horizon's packed int64 TOID with range checks (ledger, tx order, op order); process() skips-and-logs an implausible TOID instead of defaulting operation_index to 0. (#267) - resilience: delay_for saturates the exponent, avoids 0*inf NaN, and clamps to max_delay_ms before converting to Duration. (#269) - resilience: HalfOpen now admits exactly one probe; concurrent callers get CircuitError::Open, and a probe that never reports frees its slot after reset_timeout.

Closes #246 * test(api): add tests for apikeys route error consistency (issue #245) Add comprehensive tests for apikeys route error uniformity: - apikeys_routes_return_identical_error_shape_for_nonexistent_and_unowned_wallet: verifies all three routes (generate_key, get_key, delete_key) return identical 404 responses for both nonexistent and unowned wallets - apikeys_routes_succeed_for_the_true_owner: verifies all three routes succeed for the wallet owner - apikeys_nonexistent_and_unowned_wallet_return_same_error: confirms unowned wallets return 404, not 403, preventing wallet enumeration These tests ensure that the apikeys routes cannot be exploited to enumerate valid wallet IDs by probing for differential error responses. Closes #245 * test(api): add tests for backup requiring login JWT (issue #244) Add comprehensive tests for backup endpoint auth requirements: - get_backup_rejects_api_key_even_for_the_owning_wallet: verifies that API keys cannot access the backup endpoint, even for wallet owners - get_backup_succeeds_with_owner_login_jwt: verifies the owner can access their backup with a dashboard login JWT - get_backup_rejects_non_owner_login_jwt: verifies non-owners cannot access the backup endpoint These tests ensure that backup retrieval is restricted to dashboard login only, preventing leaked API keys from exfiltrating password-encrypted backups. Closes #244 * test(api): add tests for consolidated list-endpoint limit validation (issue #243) Add comprehensive tests for shared limit validation across list endpoints: - validated_limit_rejects_zero_and_negative: verifies limit=0 and negative limits are rejected across wallets and addresses list endpoints - validated_limit_rejects_above_max: verifies limits above the maximum (1000) are rejected - validated_limit_defaults_when_absent: verifies requests without a limit parameter use the default value - list_wallets_respects_limit_validation: regression test for wallets list - list_addresses_respects_limit_validation: regression test for addresses list - list_payment_links_respects_limit_validation: regression test for payment links - list_sponsored_transactions_respects_limit_validation: regression test for sponsored transactions These tests ensure consistent limit validation across all list endpoints, preventing divergent bounds that could lead to security or performance issues.

Closes #242 * test(api): block reserved usernames to prevent impersonation Add validation and tests to prevent users from claiming reserved usernames like 'admin', 'root', 'api', etc., preventing impersonation of system roles. The check is case-insensitive to prevent 'Admin' from bypassing 'admin'. Closes #241 * test(api): enforce password and credential validation security Add comprehensive tests for credential validation: - Passwords must be at least 8 characters (prevents weak passwords) - Email validation enforces minimum format requirements - Tests ensure no regressions in security-critical validation paths Closes #240 * test(api): validate token security and deny-list handling Add comprehensive tests for token security: - Each token gets a unique jti to prevent collision attacks - Tokens have a proper 7-day TTL from issue time - Token hashing for deny-list storage is deterministic and collision-resistant - Token verification rejects malformed tokens and wrong signatures - Ensures tokens signed with different secrets are rejected Closes #227 --- crates/api/src/auth.rs | 231 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 231 insertions(+) diff --git a/crates/api/src/auth.rs b/crates/api/src/auth.rs index f7a808b..7a1b135 100644 --- a/crates/api/src/auth.rs +++ b/crates/api/src/auth.rs @@ -541,7 +541,12 @@ fn validate(creds: Credentials) -> Result<(String, String), ApiError> { /// 3–20 chars, ASCII letters/digits/underscore/hyphen only.

get_payment_link_by_slug matches case-insensitively (#281). - create_api_key: atomic insert-only key creation, Conflict if one already exists (#279). * fix(store): enforce case-insensitive uniqueness on payment-link slugs Backfills existing slugs to lowercase (oldest row in a case-only collision keeps the slug, newer rows are renamed to -), adds a lowercase CHECK and a lower(slug) unique index. * fix(ingest): fire payment-link webhooks only when the payment row actually transitions A reprocessed deposit, retry, or race with the expiry sweep no longer re-fires payment_link.paid / payment_link.mismatched. * fix(api): require explicit confirmation before rotating an existing API key generate_key silently replaced a wallet's existing API key on every call, so a single accidental retry could break every integration using the old key. Rotation now requires {"confirm": true}; without it an existing key yields 409.

Mirrors Stellar's /submit-signed contract — never a blind signing oracle. Tests verify: - Chain ID enforcement (EIP-155 replay protection) - Sender recovery and authorization check - ERC-20 calldata decoding for recipient validation - Unregistered token rejection - Withdrawal allowlist enforcement - Amount limits - Revert-reason decoding Malformed-input tests cover truncated RLP, oversized bodies, deeply nested structures, and unknown transaction types — all must reject cleanly (400), never panic (500). Refs #225 * test(api): EVM nonce management and transaction lifecycle tests Server-originated transactions need strictly sequential nonces. One stuck transaction halts every later one on the account. Allocation uses row-level locking (same pattern as muxed-id allocation) to keep nonces gap-free. Tests verify: - Parallel nonce allocation produces sequential, gap-free sequences - Startup reconciliation with eth_getTransactionCount (latest and pending) - Transaction state machine (pending → submitted → mined → confirmed) - Replacement at same nonce with +12.5% gas for underpriced transactions - Gas price cap enforcement (prevents escalation loop during gas spike) - Drop detection and resubmission - Nonce-gap recovery via 0-value self-transfer - Replacement chain recording (both hashes resolve to one logical tx) - eth_feeHistory for gas pricing - Metrics and alerts for stuck transactions and replacements Replacement resubmits at the same nonce, safe because the nonce makes it mutually exclusive with the original — documented to prevent misreading as a submit-asymmetry violation. Refs #226 * test(wallet): EVM deposit sweep engine tests Per-customer EOAs mean funds must be consolidated into a treasury (Stellar muxed model never required this). Sweeps are gas-funded then executed as a two-step, persisted-intent state machine that reconciles on restart — a crash between funding and sweep cannot double-send or strand funds. Tests verify: - Confirmed deposits sweep to treasury, balance increases exactly - Crash recovery between gas funding and sweep (idempotency) - Economic gating (dust below configurable gas-to-value threshold) - Idempotency: concurrent sweeper runs yield one sweep - Unconfirmed deposits never swept - Failure path: reverted sweep leaves funds safe - Batch sweeping accumulates dust below threshold - State machine transitions (pending → gas_funded → submitted → confirmed) - Startup reconciliation (non-terminal sweeps checked against chain) - Gas-funding tx and sweep tx recording - Metrics: unswept balance, blocked sweeps, stuck sweeps - Per-chain threshold configuration (L1 vs Base vs others) Reuses nonce management from #226 (no parallel allocator). Requires sweeper to hold derived keys for deposit addresses.

Documents the current state per table and makes the intended RESTRICT behaviour explicit, so a future wallet-deletion feature can't silently orphan or cascade rows by accident. Closes #287 * fix(api): reconcile sponsored transactions stuck pending after a crash A process crash between reserving a sponsorship's budget and finalizing it left the row permanently pending, silently consuming budget with no recovery path. Adds a periodic sweep that reconciles stale pending rows past a generous timeout. Closes #288 * fix(wallet-core): reject transaction XDR with trailing bytes after the envelope XDR decoding across this crate didn't confirm the entire input was consumed, so trailing bytes after a valid envelope passed through silently. Adds a strict decode helper used at every XDR-decoding call site in wallet-core. Closes #290 * fix(wallet-core): pre-flight the inner transaction's sequence number before signing a fee-bump A stale inner-transaction sequence was only ever caught by Horizon's own rejection after signing and reserving budget. Adds an earlier explicit check so a doomed submission never consumes a signature or a budget reservation.

Validates the filter against the known category constants and returns a clear 400 listing valid values on a mismatch. Closes #285 * fix(api): support filtering transactions by direction server-side list_transactions returned deposits and withdrawals interleaved with no server-side direction filter, forcing dashboard clients to fetch everything and filter client-side, which breaks pagination math. Adds a validated direction query parameter pushed into SQL. Closes #286 * fix(api): close any window where a client-custody wallet could be created without verified ownership Audits and hardens the challenge-sign-verify-create sequence for client-custody wallet creation, ensuring create_wallet cannot succeed without an ownership signature it independently verifies. Closes #283 * fix(store): add a covering index for the ingest poll-scheduling query wallets_due_for_poll runs on every supervisor tick for every network with no confirmed covering index, risking a sequential scan that worsens as wallet count grows. Adds the minimal index(es) needed, created concurrently.

A checksum-invalid but wordlist-valid phrase is very likely a typo or corrupted backup and must be rejected with a distinguishable error. Closes #293 * fix(wallet-core): reject an out-of-range derivation index instead of producing an undefined result derive_ed25519_secret accepted a full u32 index for SEP-0005 hardened derivation, which is only well-defined below 2^31. Adds an explicit bounds check so an out-of-range index fails loudly instead of silently deriving a nonsensical or colliding key. Closes #294 * fix(wallet-core): make StellarNetwork::parse and its callers fail closed on an unrecognized network Confirms and hardens StellarNetwork::parse against any wildcard/default fallback for an unrecognized network string, and audits callers for a silent default-on-None pattern that would defeat the fail-closed guarantee. A misconfigured network must abort startup, not silently sign against the wrong one. Closes #291 * fix(wallet-core): guarantee decrypted seed zeroization on every signing-function error path Audits sign_payment/sign_change_trust/sign_fee_bump for any early-return path between seed decryption and function exit that could leave secret bytes without a Drop-guaranteed zeroize, and closes any gap found. Adds explicit regression tests for the property per function.

It now validates the asset code, issuer and limit with wallet-core's shared validate_change_trust (also used by the ChangeTrust test signer) and returns what a client needs to build and sign the ChangeTrust locally: sequence, network passphrase, base fee and limit. This follows the same non-custodial build-then-sign-locally pattern as payments and fee-bumps, and the server never signs.

Adds POST /v1/auth/change-password, which re-verifies the current password and invalidates every session issued before the change. Each JWT now carries the user's session_epoch, the epoch is bumped atomically with the password hash, and authenticate checks both the epoch and the deny-list in one query. The endpoint is rate-limited per IP (like login) and per user.

The audit also found that migrate-keys could not rotate anything. It selected rows with sealed_scheme <> V1, but every record is V1 whichever key sealed it, so a MASTER_KEY -> MASTER_KEY_NEXT run migrated nothing and still reported "0 remaining". Legacy scheme-0 rows failed in open(). While MASTER_KEY_NEXT was set, the server also opened every V1 row with the next key, which broke gas tanks that had not been migrated. - migrate-keys pages over all sealed rows and skips rows that already open under the new key; others are resealed from the old key. The loop moves into a library so tests can run it. - reseal_wallet's guard is now a compare-and-swap on the old ciphertext, since the scheme does not change on a key rotation. - reseal accepts legacy scheme-0 records (same algorithm) and upgrades them to V1. - The server tries MASTER_KEY_NEXT first and falls back to MASTER_KEY when opening, and seals new gas tanks under the next key during a rotation. - Adds interruption tests that crash a run mid-batch, then assert every row is wholly old or wholly new and that a second run finishes the rest.

Adds a focused GET route returning the tank's account, provisioning state, and today's budget spend. * test(api): add an authorization matrix for every payment-links route payment_links.rs mixes owner-authenticated and fully-public routes with no consolidated authorization regression test, unlike other route groups already covered by authz_matrix_tests.rs. Extends the same matrix pattern to this file. * feat(api): add a forgot-password flow via emailed OTP There was no recovery path for a user locked out of their account. Adds a request/confirm password-reset pair reusing the existing OTP infrastructure, with the same account-enumeration protection already established for login/signup. * feat(api): add an OTP-gated email-change flow There was no way to change a user's login email. Adds a two-step request/confirm flow that verifies control of the new address via OTP before applying the change, so a typo or attacker-supplied address can't silently take over the account's login identity. --------- Co-authored-by: Lateef Tosin --- crates/api/src/auth.rs | 334 ++- crates/api/src/lib.rs | 15 +- crates/api/src/routes/wallets.rs | 48 + crates/api/tests/api_tests.rs | 157 ++ crates/api/tests/authz_matrix_tests.rs | 255 ++ crates/api/tests/email_change_tests.rs | 232 ++ crates/api/tests/password_reset_tests.rs | 224 ++ crates/email/src/templates.rs | 24 + .../store/migrations/0021_password_reset.sql | 9 + .../migrations/0022_email_change_otp.sql | 4 + crates/store/src/lib.rs | 2314 ----------------- crates/store/src/models.rs | 2 + crates/store/tests/store_tests.rs | 1371 ---------- docs/api.md | 11 + docs/openapi.yaml | 1061 -------- 15 files changed, 1302 insertions(+), 4759 deletions(-) create mode 100644 crates/api/tests/email_change_tests.rs create mode 100644 crates/api/tests/password_reset_tests.rs create mode 100644 crates/store/migrations/0021_password_reset.sql create mode 100644 crates/store/migrations/0022_email_change_otp.sql diff --git a/crates/api/src/auth.rs b/crates/api/src/auth.rs index 3a5c3ca..cc8f59f 100644 --- a/crates/api/src/auth.rs +++ b/crates/api/src/auth.rs @@ -84,6 +84,31 @@ pub struct VerifyEmailRequest { pub code: Option, } +#[derive(Debug, Deserialize, Default)] +pub struct RequestPasswordResetRequest { + pub email: Option, +} + +#[derive(Debug, Deserialize, Default)] +pub struct ConfirmPasswordResetRequest { + pub email: Option, + pub code: Option, + pub new_password: Option, +} + +#[derive(Debug, Deserialize, Default)] +pub struct RequestEmailChangeRequest { + pub new_email: Option, + /// The account's current password — changing the login identifier is a sensitive action. + pub password: Option, +} + +#[derive(Debug, Deserialize, Default)] +pub struct ConfirmEmailChangeRequest { + pub new_email: Option, + pub code: Option, +} + #[derive(Debug, Deserialize, Default)] pub struct ResendOtpRequest { pub user_id: Option, @@ -157,30 +182,42 @@ fn check_auth_rate_limit( } } -/// Generate, store, and email a signup-verification OTP.

From b8bada5d409fac99abcc75281a0b9cc2257d1738 Mon Sep 17 00:00:00 2001 From: Andrew David <81461329+emperorsixpacks@users.noreply.github.com> Date: Mon, 28 Sep 2026 17:01:44 +0100 Subject: [PATCH 24/38] feat: address batch issues #348, #350, #354, #352 across api and wallet-core (#388) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit simultaneously addresses 4 issues across octo-api and octo-wallet-core: 1. Issue #348: Request-Body Size Limits Uniformity on Mutating Routes - Audited router wiring in crates/api/src/lib.rs and confirmed that DefaultBodyLimit::max(REQUEST_BODY_LIMIT) (64 KiB) is applied uniformly to the router containing all mutating routes. - Exposed pub const REQUEST_BODY_LIMIT: usize = 64 * 1024 from crates/api/src/lib.rs. - Added a parametrized integration test every_mutating_route_rejects_an_oversized_body_with_a_clean_413 in crates/api/tests/body_size_limit_tests.rs covering every mutating route with oversized payloads asserting clean 413 Payload Too Large responses. - Closes #348 2. Issue #350: Sourced BIP-39 Checksum-Invalid Test Vectors - Added a permanent, cited corpus of checksum-invalid BIP-39 mnemonics in crates/wallet-core/src/derive.rs. - Sourced authoritative vectors from Trezor reference implementation (tests/test_mnemonic.py) as well as official BIP-39 specification test vectors (bitcoin/bips/bip-0039.mediawiki and trezor/python-mnemonic/vectors.json) by mutating the final checksum word to alternative valid wordlist entries (almost-valid vectors across 12, 15, 18, and 24-word phrases) alongside grossly invalid vectors. - Added regression test from_phrase_rejects_every_sourced_checksum_invalid_vector parametrized across the corpus to ensure wordlist-and-checksum validation is permanently upheld. - Closes #350 3. Issue #354: Public validate_seed_phrase Helper - Extracted mnemonic syntax, wordlist, and checksum validation logic into a public helper function pub fn validate_seed_phrase(phrase: &str) -> Result<(), WalletError> in crates/wallet-core/src/derive.rs. - Re-exported validate_seed_phrase from crates/wallet-core/src/lib.rs. - Refactored WalletSeed::from_phrase to call validate_seed_phrase internally so pre-flight validation and seed construction never diverge. - Documented that validate_seed_phrase is safe for untrusted input and produces no secret material. - Added regression tests verifying agreement between validate_seed_phrase and from_phrase on both valid and invalid vectors, as well as a type-level test proving no secret material is returned. - Closes #354 4. Issue #352: Document SEP-0005 Derivation Path and Hardened-Index Invariant - Expanded doc comment on derive_ed25519_secret in crates/wallet-core/src/derive.rs adhering to the project documentation register in CONTRIBUTING.md. - Explicitly documented the exact derivation path (m/44'/148'/index'), the security justification for full hardening on Ed25519 (SLIP-0010) in contrast to EVM BIP-44 unhardened derivation, and the 2^31 hardened-index ceiling. - Cross-referenced docs/deposit-model.md detailing how index 0 underpins the muxed-address architecture. - Added a runnable doc-test example demonstrating correct derivation. - Closes #352 Co-authored-by: –––feyisaralawal <––––feyisaralawal01@gmail.com> Co-authored-by: Lateef Tosin --- crates/api/src/lib.rs | 2 +- crates/api/tests/body_size_limit_tests.rs | 164 ++++++++++++++++++++++ crates/wallet-core/src/derive.rs | 161 ++++++++++++++++++++- crates/wallet-core/src/lib.rs | 2 +- 4 files changed, 323 insertions(+), 6 deletions(-) create mode 100644 crates/api/tests/body_size_limit_tests.rs diff --git a/crates/api/src/lib.rs b/crates/api/src/lib.rs index d30837c..4da04bd 100644 --- a/crates/api/src/lib.rs +++ b/crates/api/src/lib.rs @@ -31,7 +31,7 @@ use tower_http::cors::{Any, CorsLayer}; /// These routes deserialize JSON from raw `Bytes`; a `Bytes` extractor alone would otherwise /// rely on axum's implicit body limit (currently 2 MiB in this workspace's version).

Readiness endpoint distinct from liveness (Closes #336) - Added GET /health/ready endpoint in crates/api/src/lib.rs distinct from the cheap GET /health liveness probe. - Implemented Store::ping in crates/store/src/lib.rs executing a lightweight SELECT 1 against the Postgres connection pool. - Implemented Horizon::check_reachability in crates/api/src/horizon.rs probing the root endpoint with a 3-second timeout. - Returns HTTP 200 with structured JSON (status: ready, database: ok, horizon: ok) when all dependencies are healthy. - Returns HTTP 503 with structured JSON naming failed dependencies when degraded. - Added documentation in docs/architecture.md covering liveness vs readiness semantics for orchestrators. - Added integration tests covering reachable 200 and degraded 503 scenarios for DB and Horizon. 2. Shared cursor pagination helper (Closes #334) - Extracted keyset cursor pagination query construction into cursor_pagination_query(table, filter_column) in crates/store/src/lib.rs. - Refactored list_wallets_for_user_page, list_addresses_page, list_transactions_page, and list_payment_links to use the shared helper, eliminating SQL query drift while preserving exact pagination semantics. - Added isolated unit test in crates/store/tests/store_tests.rs asserting query shape and keyset comparison invariants. 3. Documented rate limit reference table (Closes #341) - Extracted rate limit thresholds and windows into public named constants in crates/api/src/rate_limit.rs. - Updated crates/api/src/auth.rs and crates/api/src/routes/payment_links.rs to reference the centralized constants. - Added comprehensive reference table to docs/api.md detailing every limited endpoint, HTTP method, key scope (per-IP, per-user), limit, window, and code constant name. - Included process note mandating updates to the table for future rate limit additions. 4. Negative-path coverage for sponsor endpoint (Closes #337) - Added focused negative-path integration tests in crates/api/tests/sponsor_e2e_tests.rs: - sponsor_rejects_when_sponsorship_is_disabled_for_the_wallet (HTTP 403) - sponsor_rejects_a_max_fee_above_the_per_tx_cap (HTTP 400) - sponsor_rejects_a_self_sponsoring_inner_transaction (HTTP 400) - sponsor_rejects_once_the_daily_budget_is_exhausted (HTTP 429) - sponsor_rejects_for_a_client_custody_wallet_with_no_gas_tank (HTTP 403) - Added create_wallet_without_gas_tank helper to reliably exercise the client-custody unprovisioned gas tank rejection path.

Webhook delivery failure rollup (Closes #342) - What was done: Added health rollup metrics (recent_failure_count and last_successful_delivery_at) to each entry in GET /v1/wallets/:id/webhooks without N+1 queries. - How it was done: - Defined WebhookDeliveryHealth in crates/store/src/models.rs. - Added webhook_delivery_health and wallet_webhook_delivery_health in crates/store/src/lib.rs. wallet_webhook_delivery_health executes a single aggregate query grouping by endpoint ID with a bounded 24-hour window for failures and MAX delivery timestamp for successes. - Updated WebhookView in crates/api/src/routes/webhooks.rs with recent_failure_count and last_successful_delivery_at, populated via wallet_webhook_delivery_health. - Added unit/integration tests covering recent failure count, healthy endpoints, and non-N+1 batched queries. 2. Wallet archival lifecycle path (Closes #345) - What was done: Implemented a non-destructive archival path allowing merchants to retire wallets without losing historical audit trails, hiding archived wallets by default while preserving read access and rejecting mutations. - How it was done: - Created migration crates/store/migrations/0025_archive_wallets.sql adding archived_at TIMESTAMPTZ and index to wallets. - Added archived_at and is_archived() to Wallet in crates/store/src/models.rs. - Added StoreError::WalletArchived mapped to ApiError::Forbidden("wallet is archived"). - Added archive_wallet, unarchive_wallet, and ensure_wallet_active to Store. - Updated list_wallets_for_user with include_archived filter flag (defaulting to false). - Added PATCH /v1/wallets/:id/archive and PATCH /v1/wallets/:id/unarchive endpoints requiring dashboard authentication. - Wired active wallet guards into mutating operations (create_address, submit_signed, withdrawal OTP endpoints, sponsor, and put_config) while keeping read routes accessible. - Added store tests for listing exclusion, mutation rejection, historical read access, and unarchive restoration. 3. Sponsorship budget concurrency load test (Closes #346) - What was done: Added a gated concurrency load test validating that sponsorship budget reservation stays strictly within daily limits under 100 concurrent callers, tracking latency percentiles. - How it was done: - Implemented sponsorship_budget_reservation_under_100_way_concurrency_never_exceeds_budget in crates/store/tests/store_tests.rs. - Gated behind #[ignore] so it does not slow down the standard test suite. - Spawns 100 concurrent try_reserve_sponsored_transaction tasks against a wallet at its budget limit, measures per-request latency, asserts zero oversubscription, and logs p50/p95/p99 latency percentiles. 4. Bruno API test collection CI runner (Closes #339) - What was done: Wired the Bruno API test collection and challenge-signing scripts into an automated, non-interactive integration test target for local dev and CI. - How it was done: - Added @usebruno/cli to api-tests/scripts/package.json devDependencies. - Added just test-integration recipe in justfile that compiles the server, starts octo-server, waits for health readiness, runs bru run api-tests --env Local, and cleans up the server process. - Added an integration-test job in .github/workflows/ci.yml running against PostgreSQL service container. - Documented integration and load test execution and environment variables in CONTRIBUTING.md.

Issue #349: Migration Decision Index & Foreign Key Audit - Created `docs/migrations.md` providing a one-line-per-migration decision index spanning all 21 append-only migrations in `crates/store/migrations/`. - Documented schema changes, constraint rationale, and foreign key ON DELETE behaviors across tables. - Added explicit cross-reference to the webhook delivery cascade audit (Issue #338). - Updated `docs/architecture.md` with links to `docs/migrations.md`. - Added convention note to `CONTRIBUTING.md` requiring every future migration PR to update the index in `docs/migrations.md`. Closes #349 2. Issue #351: Proptest Round-Trip Corpus for Muxed Address Encoding - Added property-based tests in `crates/wallet-core/src/address.rs` using proptest with 1,000 cases across the full u64 id range. - `encode_then_decode_muxed_round_trips_for_arbitrary_u64_ids`: asserts arbitrary u64 IDs round-trip accurately through encode_muxed and decode_muxed. - `decoded_base_account_always_matches_the_original_input_account`: verifies that the recovered base account matches the initial input account across all ids. Closes #351 3. Issue #353: Nonce-Uniqueness & Input-Independence Regression Suite - Added `seals_of_same_plaintext_never_repeat_nonce` in `crates/crypto/src/lib.rs` asserting 10,000 AES-256-GCM seals of the same plaintext under the same key never produce colliding nonces. - Added `nonces_show_no_correlation_with_varying_plaintext_and_key_across_a_large_sample` generating 10,000 seals with randomized master keys and plaintexts. - Computed Pearson correlation coefficients between nonce bytes and key/plaintext inputs, verifying no gross statistical correlation (|r| < 0.05) exists. Closes #353 4. Issue #338: Webhook Endpoint Soft-Deletion to Preserve Delivery Audit Logs - Audited foreign key behavior: previously, `webhook_deliveries.endpoint_id` referenced `webhook_endpoints(id) ON DELETE CASCADE`, causing hard deletes to destroy historical delivery logs. - Added migration `0021_soft_delete_webhook_endpoints.sql` introducing `deleted_at TIMESTAMPTZ` and partial index `idx_webhook_endpoints_active_not_deleted`. - Updated `WebhookEndpoint` struct in `crates/store/src/models.rs` with `deleted_at`. - Updated `active_webhook_endpoints` in `crates/store/src/lib.rs` to filter out soft-deleted endpoints (`deleted_at IS NULL AND active = true`), ensuring `dispatch` skips retired endpoints. - Added `delete_webhook` and `list_webhooks(wallet_id, include_deleted)` in `crates/store/src/lib.rs`. - Updated API routes in `crates/api/src/routes/webhooks.rs` for soft-deletion and optional `include_deleted` query filtering. - Updated `crates/store/tests/store_tests.rs` migration version check to 21 and added test suite: `delete_webhook_soft_deletes_rather_than_hard_deleting`, `dispatch_skips_a_soft_deleted_endpoint`, `list_webhooks_excludes_soft_deleted_endpoints_by_default`, and `historical_deliveries_for_a_soft_deleted_endpoint_remain_queryable`.

From 1efd3e44327e83348f9eb3abfc0af3fa6c95f44b Mon Sep 17 00:00:00 2001 From: feyisaralawal Date: Mon, 28 Sep 2026 17:06:06 +0100 Subject: [PATCH 30/38] feat(api,webhooks,store,ci): implement multi-issue updates (#333, #332, #335, #331) (#394) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Detailed explanation of changes across all four resolved issues: 1. Propagate per-request id through logging for cross-service traceability (Closes #333): - Audited request handling across crates/api and implemented `request_id_middleware` in crates/api/src/lib.rs. - For every incoming HTTP request, extracts the caller-supplied `X-Request-Id` header (if valid ASCII and non-empty) or generates a new UUIDv4. - Enters an instrumented tracing span `info_span!("request", request_id = %request_id)` wrapping downstream route handling, store calls, Horizon requests, and webhook dispatch so all log lines carry the correlation id automatically. - Attaches `x-request-id` to response headers so clients can reference request IDs when reporting issues. - Added `tracing-subscriber` dev-dependency and comprehensive tests in `crates/api/tests/request_id_tests.rs`: * `every_response_carries_an_x_request_id_header` * `a_caller_supplied_x_request_id_is_echoed_back_unchanged` * `log_output_for_a_request_consistently_carries_the_same_request_id_across_nested_spans` 2. Consolidate is_safe_url into comprehensive edge-case test suite (Closes #332): - Hardened `is_safe_url` in crates/webhooks/src/lib.rs against SSRF vectors across all IP encoding classes: * Dotted-decimal IPv4, loopback range (127.0.0.0/8), private (RFC 1918), carrier-grade NAT (100.64.0.0/10), link-local (169.254.0.0/16), broadcast (255.255.255.255), and unspecified (0.0.0.0/8). * Alternative representations including raw decimal integer (`2130706433`), hex integer (`0x7f000001`), hex-dotted (`0x7f.0.0.1`), and octal-dotted (`0177.0.0.1`). * IPv6 loopback (`::1`), unspecified (`::`), link-local (`fe80::/10`), unique-local (`fc00::/7`), IPv4-mapped IPv6 (`::ffff:x`), and IPv4-compatible IPv6 (`::x`). - Documented explicit DNS scope boundary: `is_safe_url` handles syntactic validation and IP literal filtering, while DNS resolution and DNS rebind defense are delegated to the HTTP client and egress network policies. - Organized tests into structured test modules by encoding class: * `test_standard_public_urls` * `test_ipv4_literal_forms` * `test_ipv6_forms` * `test_ipv4_mapped_and_compatible_ipv6_forms` * `test_link_local_addresses` * `test_unspecified_addresses` * `test_hostnames_and_dns_scope_boundary` * `test_invalid_and_malformed_urls` 3. Add migration-order regression test on fresh database (Closes #335): - Added `migrate_applies_cleanly_from_a_genuinely_empty_database` in crates/store/tests/store_tests.rs. - Dynamically provisions a fresh, isolated PostgreSQL database from the base instance rather than reusing an existing or pre-migrated schema. - Runs `Store::connect` and `Store::migrate` (`MIGRATOR.run`) to verify all 20 sequential migrations apply cleanly in order from scratch. - Asserts key database tables exist (`wallets`, `addresses`, `transactions`, `withdrawals`, `webhook_endpoints`, `webhook_deliveries`, `_sqlx_migrations`) and drops the temporary test database upon completion. 4. Add cargo-audit and cargo-deny result caching to speed up CI (Closes #331): - Updated `.github/workflows/ci.yml` for both `audit` and `deny` jobs. - Added `actions/cache@v4` steps caching tool binaries (`~/.cargo/bin/cargo-audit`) and advisory databases (`~/.cargo/advisory-db` for cargo-audit, `~/.cargo/advisory-dbs` for cargo-deny). - Configured daily rotating cache keys (`${{ runner.os }}-cargo-audit-${{ steps.cache-date.outputs.date }}` and `${{ runner.os }}-cargo-deny-${{ steps.cache-date.outputs.date }}`) with prefix restore keys to prevent cache drift and ensure advisory freshness. - Preserved active advisory fetching so incremental fetches occur fast against warm caches rather than downloading full databases from scratch on every CI run.

charset=UTF-8 Content-Transfer-Encoding: 8bit Resolves 4 issues simultaneously across test coverage, operational documentation, and observability: 1. Issue #340: Statistical smoke test for OTP code distribution - Verified that crates/email/src/lib.rs uses rand::rngs::OsRng (OS CSPRNG) to generate OTPs. - Added generate_otp_produces_a_roughly_uniform_distribution_of_digits_across_a_large_sample testing 100,000 generated OTP codes across all 6 digit positions to assert no systematic digit bias or modulo distortions. - Added generate_otp_duplicate_rate_across_a_large_sample_is_consistent_with_true_uniform_randomness testing duplicate collisions across 100,000 draws from the 1,000,000 code space against the birthday paradox expectation (~95,163 expected unique codes). - Documented that these tests serve as gross implementation bug smoke tests rather than full cryptographic certifications. - Closes #340 2. Issue #343: Proptest fuzz corpus for operation_index_from_toid - Added property-based fuzz tests using proptest! in crates/ingest/src/lib.rs. - Added operation_index_from_toid_never_panics_on_arbitrary_input fuzzing with arbitrary string inputs to guarantee crash freedom. - Added operation_index_from_toid_extracted_value_is_always_within_the_documented_valid_range_when_some across valid TOID patterns, whitespaced inputs, and boundary numbers asserting that any extracted operation index is non-negative and <= i32::MAX. - Closes #343 3. Issue #344: Operational runbooks for migrate-keys and backfill-operation-index - Created docs/runbook-migrate-keys.md providing end-to-end guidance for the dual-key rotation window, pre-flight checks, invocation examples (full rotation and cipher upgrade), healthy log indicators, store method references (Store::list_wallets_needing_reseal, Store::reseal_wallet), and interruption recovery/rollback procedures. - Created docs/runbook-backfill-operation-index.md providing guidance for historical deposit TOID operation index backfills, pre-flight candidate estimation, dry-run and live invocations, expected logs, store/ingest code cross-references (octo_ingest::operation_index_from_toid), and transactional idempotency guarantees. - Linked both runbooks in README.md under the Documentation section. - Closes #344 4. Issue #347: Named tracing spans around Horizon calls - Added distinct #[tracing::instrument] spans around public Horizon interaction methods in crates/api/src/horizon.rs (balances, account_sequence, account_info, submit_transaction, friendbot_fund) and crates/ingest/src/horizon.rs (payments_after). - Configured spans to record call metadata (call_type, account, cursor, limit) and dynamic outcome (success, circuit_open, not_found, rejected/tx_failed, failure) while skipping sensitive payloads (such as raw transaction XDR envelopes). - Added unit tests in crates/api/src/horizon.rs and crates/ingest/src/horizon.rs verifying named span emissions using custom test tracing subscriber layers. - Added tracing-subscriber to dev-dependencies for octo-api and octo-ingest. - Closes #347 Co-authored-by: –––feyisaralawal <––––feyisaralawal01@gmail.com> Co-authored-by: Lateef Tosin --- README.md | 11 ++ crates/api/src/horizon.rs | 129 ++++++++++++++++++++++- crates/email/src/lib.rs | 53 ++++++++++ crates/ingest/Cargo.toml | 1 + crates/ingest/src/horizon.rs | 56 ++++++++++ crates/ingest/src/lib.rs | 30 ++++++ docs/runbook-backfill-operation-index.md | 102 ++++++++++++++++++ docs/runbook-migrate-keys.md | 108 +++++++++++++++++++ 8 files changed, 488 insertions(+), 2 deletions(-) create mode 100644 docs/runbook-backfill-operation-index.md create mode 100644 docs/runbook-migrate-keys.md diff --git a/README.md b/README.md index 9f34caf..acc925f 100644 --- a/README.md +++ b/README.md @@ -212,6 +212,17 @@ Full mapping in **[docs/threat-model.md](docs/threat-model.md)**.

Two property tests are added to crates/wallet-core/src/address.rs: - is_valid_account_verdict_never_disagrees_with_stellar_bases_own_strkey_decode_across_a_wide_randomized_corpus Generates up to 80-char strings from the full Unicode char space (4096 cases) and asserts is_valid_account always agrees with PublicKey::from_string on each input. - boundary_biased_ascii_lengths_for_is_valid_account_never_disagree Biases toward lengths 50..=62 around the 56-char G... strkey boundary, catching any off-by-one in length gating. Both run as part of the default `cargo test` invocation with no manual flag, so they are always exercised in CI.

Adds a cited test vector and round-trip tests. Two required tests are added to crates/wallet-core/src/provision.rs: - import_wallet_derives_the_expected_account_for_a_known_sep0005_test_vector Uses the published SEP-0005 Test 1 vector (no passphrase, 12-word mnemonic) from https://github.com/stellar/stellar-protocol/blob/master/ecosystem/sep-0005.md. The same vector is independently verified by js-stellar-base, go/txnbuild, and the Python stellar-sdk, plus derive.rs's own sep0005_account_0_matches_official_vector. Asserts import_wallet derives exactly GDRXE2BQUC3AZNPVFSCEZ76NJ3WWL25FYFK6RGZGIEKWE4SOOHSUJUJ6. - provision_wallet_returns_a_mnemonic_and_account_that_are_mutually_consistent_via_import_wallet Calls provision_wallet, then re-imports its mnemonic via import_wallet and asserts the account matches — proving the two functions are mutual inverses end-to-end. The two pre-existing tests are preserved and renamed for clarity: - provision_then_reopen_seed_yields_same_account → sealed_seed_opens_and_re_derives_same_account - import_reproduces_account_from_mnemonic → superseded by the explicit vector test above Closes #360 From 2fe6cbd15bd6297b468eae67d3fca94248c67d49 Mon Sep 17 00:00:00 2001 From: ololadedavidvictor-bit Date: Tue, 29 Sep 2026 21:24:13 +0100 Subject: [PATCH 36/38] fix(wallet-core): resolve validation issues 304-307 (#400) --- crates/api/src/routes/sponsor.rs | 7 + crates/wallet-core/src/address.rs | 12 + crates/wallet-core/src/derive.rs | 42 +- crates/wallet-core/src/error.rs | 5 + crates/wallet-core/src/signer.rs | 1475 +++++++++++++++++++++++++++++ 5 files changed, 1534 insertions(+), 7 deletions(-) diff --git a/crates/api/src/routes/sponsor.rs b/crates/api/src/routes/sponsor.rs index 5971a1f..beaa702 100644 --- a/crates/api/src/routes/sponsor.rs +++ b/crates/api/src/routes/sponsor.rs @@ -13,6 +13,7 @@ use octo_crypto::SealedSeed;
