REDHAT-BUG-2514227: High severity Red Hat Red Hat Advanced Cluster Management (RHACM) vulnerability

Published Aug 11, 2026
·
Updated

A flaw was found in the multicloud-integrations component of Red Hat Advanced Cluster Management (RHACM). The Application propagation controller takes the tenant-controlled ocm-managed-cluster annotation verbatim from an Application CR and uses it as the ManifestWork namespace without authorization checks. The only validation is a bare existence check on the target ManagedCluster. A tenant with Application create permissions in any hub namespace can generate ManifestWorks targeting arbitrary managed clusters, resulting in spoke cluster-admin ArgoCD syncing attacker-controlled manifests.
