From bc69de1491e958fc7e6ed9ae01022dc275e3c263 Mon Sep 17 00:00:00 2001 From: "claude[bot]" <41898282+claude[bot]@users.noreply.github.com> Date: Thu, 23 Jul 2026 23:37:18 +0000 Subject: [PATCH] =?UTF-8?q?fix(security):=20harden=20subprocess/bind/try-p?= =?UTF-8?q?ass/tmp=20+=20justify=20test=20FPs=20=E2=80=94=20port=20to=20PR?= =?UTF-8?q?=20#93?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cherry-port of commit 77eb667 (from the sec-83-bandit fix branch) onto the chore/a2a-prod-rollout-prep PR branch, with resolved database.py conflict and the @pytest.mark.asyncio decorator added for the new allowlist test class. Root cause of security-scan failure: bandit -r . --skip B101 exits 1 whenever it finds any issue. The test_residual_authz.py file (and several others) had unannotated false-positives that triggered B105/B404/B603/B607/B104/B108/B110. Changes applied: - B105: add # nosec B105 to JWT_SECRET test fixtures in test_residual_authz.py, test_auth_authz.py, and test_hierarchy_ws_authz.py - B404/B603/B607: annotate subprocess imports + calls (shell=False, static argv) in claude_code_wrapper.py, claude_sdk_manager.py, git_workflow_manager.py - B104: env-gate uvicorn host in simple_main.py + main_with_hierarchy.py; annotate Docker port-map string in container_manager.py - B108: replace hard-coded /tmp in model_configuration.py with tempfile.gettempdir() + FUZEAGENT_KEY_DIR env; annotate sandbox tmpfs mount + test path - B110: replace bare except/pass with narrowed excepts + debug logging in container_manager.py and main.py websocket broadcast paths - database.py: move column allowlist validation before DB connection (fail-fast) - Add tests/test_database_update_allowlist.py with @pytest.mark.asyncio decorator Fixes security-scan CI failure on PR #93.
