Short explanation
Traefik v3.7.13 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 fails to apply access-control annotations.
Unauthenticated attackers reaching the HTTP entry point with the Ingress host can access backends protected by security annotations without any activity being logged.
What should be done?
- Follow the vendor security advisories and guidance from Traefik
- Monitor official advisories for version update details

Show the technical text from the sources
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.
