ngress-nginx controller - configuration injection via unsanitized auth-tls-match-cn annotation
Quick fix
GHSA-823x-fv5p-h7hw — k8s.io/ingress-nginx: upgrade to the fixed version with the command below.
go get k8s.io/ingress-nginx@v1.11.5Details
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.)
