Description Avinash Hanwate 2023-07-28 05:00:50 UTC 
A security issue was discovered in Kubernetes where a user that can create pods on Windows nodes running kubernetes-csi-proxy may be able to escalate 
to admin privileges on those nodes. Kubernetes clusters are only affected if they include Windows nodes running kubernetes-csi-proxy. Any kubernetes environment with Windows nodes that are running kubernetes-csi-proxy is impacted. This is a common default configuration on Windows nodes. Run kubectl get nodes -l kubernetes.io/os=windows to see if any Windows nodes are in use.
