Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Ingress middleware pipelines failed to consistently apply Access JWT validation handlers, leaving downstream services exposed to unauthenticated requests. Developers must ensure all routing pipelines integrate verification handlers before proxying traffic.
Denial of Service: QUIC, TCP, and UDP tunnels suffered from indefinite blocking, resource leaks, and panics due to missing connection write timeouts and deferred stream cleanup during handshake or context cancellation.
Path Traversal: Improper reconstruction of URL paths allowed path traversal bypasses. Relinking request paths relative to base URLs must utilize safe base normalization and strict URL parsing to defend against traversal strings.
