Traefik ForwardAuth Authentication Bypass via X-Forwarded-Prefix Spoofing

A high-severity authentication bypass vulnerability exists in Traefik's `ForwardAuth` middleware when `trustForwardHeader=false` is configured and Traefik is deployed behind a trusted upstream proxy; Traefik fails to sanitize the `X-Forwarded-Prefix` header, allowing attackers to spoof a trusted prefix value and gain unauthorized access to protected backend routes.
