Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
JWT Algorithm Confusion: Critical flaw where HMAC algorithm could be used with a public key verifier, allowing token forgery. The fix adds a check to skip HMAC, but sibling JWT validation paths may not enforce this.
Auth Bypass: Unsigned Base64 tokens allowed forgery and unauthorized access. Fix switched to signed JWT with HMAC-SHA256 and expiration; other token-generation paths may still use weak signing.
SQL Injection: Multiple SQL injection variants were fixed with parameterized queries and input validation, but other query-construction paths (e.g., error-based) may still concatenate input.
