What is CVE-2026-15218?

CVE-2026-15218 is a high-severity vulnerability in Red Hat OpenShift AI 3.4, published on 17 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.

Official description

A flaw was found in the maas-api and maas-controller ServiceAccounts within Red Hat OpenShift AI.

This could lead to full cluster administrator privileges through the creation of new ClusterRoleBindings or the disclosure of sensitive information by accessing all secrets across the cluster.
