5.0 mediumEPSS 0.2%

Medium (5.0) in redhat openshift container platform. EPSS 0.2% chance of exploitation in the next 30 days.

A flaw was found in OpenShift Container Platform. Completed pods with restartPolicy: Never do not count toward ResourceQuota pod limits, and Kubernetes events are not quota-scoped. A non-privileged user who can create pods in a namespace can exploit this to generate a large volume of events that accumulate in etcd, causing API server performance degradation across the cluster.
