- Ingress-NGINX Admission Controller v1.11.1 - FD Injection to RCE2026-02-04 · remote · multiple
Impact
A security issue was discovered in [ingress-nginx](https://github.com/kubernetes/ingress-nginx) where the `auth-tls-match-cn` Ingress annotation can be used to inject configuration into nginx. This can lead to arbitrary code execution in the context of the ingress-nginx controller, and disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)
