medium Nessus Plugin ID 313202

Synopsis

The remote macOS host is affected by an information disclosure vulnerability.

Description

The version of Traefik installed on the remote macOS host is prior to 2.11.44 or 3.x prior to 3.6.15. It is, therefore, affected by an information disclosure vulnerability:

 - Traefik's errors middleware forwards Authorization and Cookie headers to separate error page service.
 (CVE-2026-41181)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Traefik version 2.11.44, 3.6.15, or later.
