Privilege escalation in Red Hat Multicluster Global Hub
CVE-2026-110744
A flaw was found in multicluster-global-hub-operator-bundle. The operator is configured with overly broad role-based access control (RBAC) permissions that grant cluster-wide impersonation of arbitrary users, groups, and service accounts without restriction. An attacker who compromises the operator or obtains its service account credentials can exploit this flaw to achieve privilege escalation, gaining full administrative control over the cluster.
