low Tenable Self-Hosted Container Security Plugin ID 445741

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 3.6.11 until 3.6.25 and 3.7.10,
Traefik's BasicAuth middleware in pkg/middlewares/auth/basic_auth.go deduplicates concurrent password
checks with a singleflight key built from the delimiter-free concatenation of password and secret,
allowing an attacker who has a valid credential and the stored hash to authenticate as an unconfigured
username when headerField trusts the forwarded identity. This issue is fixed in 3.6.25 and 3.7.10.
(CVE-2026-71326)

Solution

Update the github.com/traefik/traefik/v3 library and its related packages to version 3.6.25 or later.
