SCA: security update for github.com/traefik/traefik/v3 (GHSA-6p8f-p8j2-rqmv)

medium Tenable Self-Hosted Container Security Plugin ID 445738

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. From v3.7.0 prior to v3.7.6, Traefik's
 Kubernetes Gateway API provider may resolve two accepted HTTPRoutes that target the same backend
 Service:port but configure different backendRef filters to the same child service and apply only one
 route's filter set to all requests reaching that backend. In Gateway deployments where backendRef filters
 set security-sensitive headers, such as tenant identity, authorization context, or values the backend
 trusts, an attacker who can create an accepted HTTPRoute sharing the same backend Service:port may cause
 their route's filter context to be applied to another route's requests, potentially crossing namespace
 boundaries when a ReferenceGrant permits cross-namespace targeting. This issue is fixed in version v3.7.6.
 (CVE-2026-54765)

Solution

Update the github.com/traefik/traefik/v3 library and its related packages to version 3.7.6 or later.
