CVE-2026-18608Network attack vector

Cluster-admin escalation via overprivileged operator ClusterRole

Published Aug 10, 2026 · Updated Aug 10, 2026

Privilege escalation in Red Hat OpenShift AI 3.3 allows attackers controlling a DSPO pod to gain cluster-admin privileges. The operator's ClusterRole grants its ServiceAccount unnecessary cluster-wide pods/exec access and CRUD over ClusterRoles and ClusterRoleBindings. Exploitation requires prior compromise of the DSPO pod; the granted rights expose cluster resources to command execution, reading, and modification.
