CVE-2026-10533 PUBLISHED

Openshift: openshift: non-admin user can bypass resourcequota and flood etcd with events causing cluster-wide api degradation

Assigner: redhat
Reserved: 01.06.2026 Published: 01.06.2026 Updated: 01.06.2026

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.
