Go parses this into `URL.Opaque` with an empty `URL.Path`, so Traefik evaluates all routing, path-sanitization, middleware and access-log decisions against a path that normalizes to `/`, while the proxy forwards the attacker's original target byte-for-byte to the backend. Router path/prefix guards, `forwardAuth` path-scoped policies and the `encodedCharacters` hardening never see the real target, and the access log records every such request as `GET / HTTP/1.1`. Against a backend that resolves a rootless target as a path, this yields cross-vhost routing bypass, path-scoped authorization bypass and access-log evasion — unauthenticated, with stock entrypoint defaults.\n\nTraefik v3.0 through v3.6 are end-of-life and are also affected; they will not receive a fix on their own line.
