Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Recurring identity forgery and validation bypasses across the auth filter family: injected identity headers, empty claims maps, non-unique group identifiers, cookie domain confusion, and JWT predicates that don't verify signatures.
Denial of Service: Resource exhaustion via missing timeouts, goroutine/connection leaks, unbounded splits, and panics. The proxy layer repeatedly lacked read/write/backend timeouts and cancellation propagation.
SSRF: Kubernetes ExternalName services and dynamic backend filters allow client-controlled backend URLs, enabling SSRF. Multiple fixes added validation or feature-flag guards, but the feature was later re-enabled.
