CVE-2026-65600

A flaw was found in Traefik. An unauthenticated remote attacker can bypass authentication due to a path traversal vulnerability in the ReplacePathRegex middleware. When this middleware is misconfigured, it forwards un-normalized paths, allowing a backend to resolve them to protected routes and...

CVE-2026-54765

A flaw was found in Traefik's Kubernetes Gateway API provider. An attacker capable of creating an accepted HTTPRoute that shares the same backend Service and port could exploit this vulnerability. The system may incorrectly apply the attacker's route filter context to another route's requests,...

CVE-2026-54764

A flaw was found in Traefik, an HTTP reverse proxy and load balancer. The ForwardAuth middleware, even when configured to not trust forwarded headers, incorrectly uses the original incoming request to determine the X-Forwarded-Port header sent to the authentication service. This allows an...

CVE-2026-65601

A flaw was found in Traefik, a cloud-native edge router. A low-privileged user in a Kubernetes environment could exploit a namespace confusion vulnerability within the Kubernetes Gateway API provider. This flaw allows an attacker to bypass security controls by incorrectly binding a Traefik...
