SCA: security update for github.com/traefik/traefik/v2, github.com/traefik/traefik/v3 (GHSA-cxjq-mrr5-89rv)

high Tenable Cloud Security Plugin ID 445743

Description

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

- Traefik versions <= v2.11.51, >= v3.6.0 <= v3.6.22, and >= v3.7.0 <= v3.7.6 contain an authentication
bypass via path traversal in the ReplacePathRegex middleware. When ReplacePathRegex is configured with a
regex that captures user-controlled path segments without a mandatory path separator (e.g. regex
"^/api(.*)", replacement "/$1"), the middleware forwards the replaced path to the backend without
validating that it matches its normalized form. An unauthenticated remote attacker can send a crafted
request (e.g. GET /api../admin) that produces an un-normalized path such as /../admin, which a backend
that normalizes paths resolves to a protected route, bypassing authentication middleware. Fixed in
v2.11.52, v3.6.23, and v3.7.7. (CVE-2026-65600)

Solution

Update the github.com/traefik/traefik/v2 library and its related packages to version 2.11.52 or later.
