CRITICAL 9.9EPSS 0.66%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.66%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

When RKE provisions a cluster, it stores the cluster state in a configmap called `full-cluster-state` inside the `kube-system` namespace of the cluster itself. The information available in there allows non-admin users to escalate to admin.
