Traefik from 3.7.0-ea.1 before 3.7.15 contains an authentication bypass vulnerability in the Kubernetes Ingress NGINX provider that silently disables mTLS configured via the auth-tls-secret annotation. When another Ingress declares a path on the same host without matching auth-tls settings, Traefik falls back to default TLS options, letting unauthenticated attackers reach backends requiring client certificates.
