CVE-2026-15140Network attack vector

Cluster privilege escalation via unenforced admission rights

Published Sep 9, 2026 · Updated Sep 9, 2026

Privilege escalation in Pure Storage Portworx Operator 26.3.1 and earlier allows remote authenticated users to gain cluster-wide access. During initial OpenShift StorageCluster provisioning, the operator accepts create, update, or delete requests without enforcing cluster-admin rights. A user with limited namespace-scoped permissions can trigger broader Kubernetes access, but only during that provisioning window.
