Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Authentication Bypass: Insecure cryptographic verification due to missing explicit signature algorithms allowed potential algorithm-switching attacks during token validation. Developers must enforce strict expected algorithms on key load paths.
Authentication Bypass: Partial or incomplete cookie-based token extractions did not enforce strict element-count verification, allowing attackers to bypass authentication checks using fragmented payloads.
Denial of Service: Unhandled exceptions thrown during the parsing of malformed but structurally correct JWTs caused unexpected application-wide crashes instead of graceful validation failures.
