SCA: security update for github.com/traefik/traefik/v3 (GHSA-8rxv-jg7p-wvg3)

high Tenable Self-Hosted Container Security Plugin ID 445740

Description

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

 - Traefik versions >= v3.7.0 and <= v3.7.7 contain a path traversal vulnerability in the Kubernetes Ingress
 NGINX provider's RewriteTarget middleware (generated from the nginx.ingress.kubernetes.io/rewrite-target
 annotation). When an Ingress path uses a regex that captures attacker-controlled text without requiring a
 path separator (e.g., path /api(.*) with rewrite target /$1), a crafted request such as /api../admin
 matches the public router, is rewritten to a dot-segment traversal path (/../admin), and is forwarded
 without post-replacement normalization validation. A backend that normalizes dot segments resolves the
 path to a protected endpoint (e.g., /admin) reachable only through a separate router secured with
 BasicAuth, DigestAuth, or ForwardAuth, resulting in route-level authentication bypass. The issue is fixed
 in v3.7.8. (CVE-2026-67309)

Solution

Update the github.com/traefik/traefik/v3 library and its related packages to version 3.7.8 or later.
