Kubernetes is vulnerable to privilege escalation when 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.

|---|---|---|---|
| github.com/kubernetes-csi/csi-proxy | le | 1.1.2 | |
