CVE-2026-10533 (GCVE-0-2026-10533)

Vulnerability from cvelistv5 – Published: 2026-06-01 13:19 – Updated: 2026-06-08 14:13

Title

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

Summary

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.

Severity
