Traefik < 2.11.43 / 3.x < 3.6.14 Multiple Vulnerabilities

The version of Traefik installed on the remote macOS host is prior to 2.11.43 or 3.x prior to 3.6.14. It is, therefore, affected by multiple vulnerabilities: - An authentication bypass via StripPrefixRegex and ForwardAuth dot-segment normalization. When StripPrefixRegex processes URLs with...

CVE-2026-39858

Traefik is an HTTP reverse proxy and load balancer. Prior to versions 2.11.43, 3.6.14, and 3.7.0-rc.2, there is a high severity authentication bypass vulnerability in Traefik's ForwardAuth and snippet-based authentication middleware. Traefik's forwarded-header sanitization logic targets only...

CVE-2026-39858

Traefik vulnerable to a high-severity authentication bypass via forwarded alias headers. The sanitization logic targets only canonical headers (e.g., X-Forwarded-Proto) and does not strip or normalize alias forms using underscores (e.g., X_Forwarded_Proto). When an auth backend normalizes undersc...
