Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Middleware validation failures allowed execution to proceed downstream even when authentication or authorization checks failed, completely bypassing security gates.
Auth Bypass: Subrouters, particularly those handling OAuth2 and OpenID, historically missed essential security middlewares, leading to exposed backend endpoints.
IP Address Spoofing: Insecure handling of X-Forwarded-For headers allowed clients to spoof IP addresses, potentially bypassing rate limiting or geographic policies unless limited to trusted environments.
