SCA: security update for github.com/traefik/traefik/v2, github.com/traefik/traefik/v3 (GHSA-f52w-8j3h-j724)

high Tenable Cloud Security Plugin ID 447923

Description

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

 - Traefik is an open source HTTP reverse proxy and load balancer. Prior to 2.11.57, and 3.7.13, Traefik
 accepts a rootless HTTP/1 request target that Go stores in URL.Opaque while leaving URL.Path empty. The
 rewriteRequestBuilder path evaluates routing, path sanitization, forwardAuth, encodedCharacters, and
 access logging against a path normalized to / but forwards URL.Opaque verbatim to the backend, allowing
 cross-vhost routing bypass, path-scoped authorization bypass, and access-log evasion when the backend
 interprets the opaque target as a path. This issue is fixed in 2.11.57 and 3.7.13. (CVE-2026-88009)

Solution

Update the github.com/traefik/traefik/v2 library and its related packages to version 2.11.57 or later.
