ingress-nginx admission controller RCE escalation
Quick fix
GHSA-mgvx-rpfc-9mpv — 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 Kubernetes where under certain conditions, an unauthenticated attacker with access to the pod network can achieve arbitrary code execution in the context of the ingress-nginx controller. This can lead to disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)
