CVE-2026-114656 · Traefik before 2.11.58 and 3.7.13 mTLS Bypass via Negated Host Matcher
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Traefik before 2.11.58 and 3.7.13 contains an authentication bypass vulnerability that allows unauthenticated clients to skip client-certificate checks because negated Host matchers are counted as served domains. Attackers can reach backends protected by RequireAndVerifyClientCert when a router rule with !Host() creates a TLS options conflict that falls back to the default options.
