Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Numerous fixes target registration, login, token issuance, and OAuth flows, showing a recurring failure to enforce fail-closed defaults and proper authorization checks.
Auth Bypass: API key middleware repeatedly missed authorization checks (group availability, quota/expiry, IP ACL), allowing continued access after revocation or to restricted groups.
Information Disclosure: Audit logs repeatedly stored plaintext credentials (session cookies, request bodies), requiring redaction and omission routes to prevent leakage.
