🚨 Three Traefik flaws affect HTTP routing and access controls. CVE-2026-114640: mTLS spoofing. CVE-2026-114636: authentication bypass. CVE-2026-114635: SNI check bypass. Review affected Ingress configurations and upgrade. 🔎 https://exploitgrid.net

NVD description
Traefik v3.7.13 before v3.7.14 contains an access-control bypass in the Kubernetes Ingress NGINX provider, where the HTTP router generated for ssl-passthrough Ingresses on non-TLS entry points never applies the Ingress's access-control annotations. Unauthenticated attackers reaching the HTTP entry point with the Ingress host can access backends protected by auth-type, auth-url, or whitelist-source-range annotations, with nothing logged.
