SCA: security update for github.com/traefik/traefik/v3 (GHSA-4mr2-fg2p-w63c)

medium Tenable Self-Hosted Container Security Plugin ID 443707

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Traefik is an HTTP reverse proxy and load balancer. From 3.7.0-ea.1 until 3.7.5, there is a medium
 severity vulnerability in Traefik's Kubernetes Ingress NGINX provider that causes affected routes to fail
 open. When an Ingress explicitly enables BasicAuth or DigestAuth through the supported
 nginx.ingress.kubernetes.io/auth-type and auth-secret annotations, but the referenced auth Secret cannot
 be resolved or parsed, Traefik logs the resolution error, skips installing the authentication middleware,
 and still emits a router to the backend service. A route that operators intended to protect is therefore
 published to the data plane without its authentication control, allowing unauthenticated access to the
 backend. The trigger is an invalid or unresolved auth dependency — a missing, malformed, unreadable, or
 policy-denied Secret — rather than an intentionally unprotected route. This vulnerability is fixed in
 3.7.5. (CVE-2026-54762)

Solution

Update the github.com/traefik/traefik/v3 library and its related packages to version 3.7.5 or later.
