Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Traefik is an HTTP reverse proxy and load balancer. Versions 2.11.40 and below, 3.0.0-beta1 through
3.6.11, and 3.7.0-ea.1 comtain BasicAuth middleware that allows username enumeration via a timing attack.
When a submitted username exists, the middleware performs a bcrypt password comparison taking ~166ms. When
the username does not exist, the response returns immediately in ~0.6ms. This ~298x timing difference is
observable over the network and allows an unauthenticated attacker to reliably distinguish valid from
invalid usernames. This issue is patched in versions 2.11.41, 3.6.11 and 3.7.0-ea.2. (CVE-2026-32595)
Solution
