CVE-2026-54764 (opens in a new tab)How to fix?
There is no fixed version for Minimos:latest traefik-2.
NVD Description
Note: Versions mentioned in the description apply only to the upstream traefik-2 package and not the traefik-2 package as distributed by Minimos.
See How to fix? for Minimos:latest relevant fixed versions and status.
Traefik is an HTTP reverse proxy and load balancer. Prior to v2.11.51, v3.6.22, and v3.7.6, Traefik's ForwardAuth middleware, even when configured with trustForwardHeader: false, derives the X-Forwarded-Port header sent to the authentication service from the original incoming request instead of the sanitized forwarded request. As a result, an unauthenticated remote attacker can inject an X-Forwarded-Proto: https header over a plain HTTP connection and cause Traefik to forward X-Forwarded-Port: 443 to the authentication service, bypassing port-based authorization checks. This issue is fixed in versions v2.11.51, v3.6.22, and v3.7.6.
