+  "details": "### Vulnerability\n\nhttps://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L463-L465\n\nhttps://github.com/samrocketman/jervis/blob/157d2b63ffa5c4bb1d8ee2254950fd2231de2b05/src/main/groovy/net/gleske/jervis/tools/SecurityIO.groovy#L495-L497\n\nUses `PKCS1Encoding` which is vulnerable to Bleichenbacher padding oracle attacks. Modern systems should use OAEP (Optimal Asymmetric Encryption Padding).\n\n### Impact\n\nSeverity is considered low for internal uses of this library but if there's any consumer using these methods directly then this is considered critical.\n\nAn attacker with access to a decryption oracle (e.g., timing differences or error messages) could potentially decrypt ciphertext without knowing the private key.\n\nJervis uses RSA to encrypt AES keys in local-only storage inaccessible from the web.  The data stored is GitHub App authentication tokens which will expire within one hour or less.\n\n### Patches\n\nJervis patch will migrate from `PKCS1Encoding` to `OAEPEncoding`.\n\nUpgrade to Jervis 2.2.\n\n### Workarounds\n\nNone\n\n### References\n\n- [Bleichenbacher's Attack on PKCS#1](https://en.wikipedia.org/wiki/Adaptive_chosen-ciphertext_attack)",
