SCA: security update for github.com/traefik/traefik/v2, github.com/traefik/traefik/v3 (GHSA-gm3x-23wp-hc2c)

medium Tenable Cloud Security Plugin ID 436291

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. For versions prior to 2.11.32 and 2.11.31 through
 3.6.2, requests using PathPrefix, Path or PathRegex matchers can bypass path normalization. When Traefik
 uses path-based routing, requests containing URL-encoded restricted characters (/, \, Null, ;, ?, #) can
 bypass the middleware chain and reach unintended backends. For example, a request to
 http://mydomain.example.com/admin%2F could reach service-a without triggering my-security-middleware,
 bypassing security controls for the /admin/ path. This issue is fixed in versions 2.11.32 and 3.6.3.
 (CVE-2025-66490)
