Echo: github.com/traefik/traefik/v3: security update to 3.7.13

high Tenable Self-Hosted Container Security Plugin ID 458955

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 3.2.0 until 3.7.13, Traefik
 entrypoint defenses aliasHeadersStrategy, underscoreHeadersStrategy, and forwardedHeaders inspect
 req.Header but not req.Trailer, allowing an unauthenticated client to submit an aliasing or trusted header
 name in an HTTP/1.1 chunked trailer or an HTTP/2 trailer. When the retry or buffering middleware reads the
 body before the reverse proxy clones the request, the attacker-controlled trailer value reaches a backend
 that merges trailers into the header namespace, bypassing the documented delete or reject behavior and
 potentially spoofing identity or forwarded routing data. This issue is fixed in 3.7.13. (CVE-2026-88004)

Solution

Update the github.com/traefik/traefik/v3 library and its related packages to version 3.7.13 or later.
