SCA: security update for github.com/traefik/traefik/v3 (GHSA-v67p-phpq-fc8x)
high Tenable Cloud Security Plugin ID 447921
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.See Also
