github.com/traefik/traefik: Traefik: Incorrect authorization due to HTTP/2 protocol confusion
Einstufung nach Quelle
Trivys eigenes Label ist CRITICAL. Kritisch laut NVD, Red Hat. Niedriger laut GHSA (hoch).
Beschreibung
Traefik is an open source HTTP reverse proxy and load balancer. From 2.11.26 until 2.11.57 and 3.7.13, Traefik forwards a client-supplied Connection header requesting Upgrade, the Upgrade: h2c token, and HTTP2-Settings to a shared backend. If the backend accepts h2c and returns 101 Switching Protocols, Traefik enters a raw tunnel and no longer applies routers, BasicAuth, ForwardAuth, IPAllowList, RateLimit, access logging, metrics, or tracing to later HTTP/2 requests, allowing an unauthenticated request through an unprotected route to reach protected paths on the same backend. This issue is fixed in 2.11.57 and 3.7.13.
