CVE-2026-72526 is a critical vulnerability in Red Hat Advanced Cluster Management for Kubernetes 2.11's multicloud-integrations component. The Application propagation controller improperly validates the ocm-managed-cluster annotation from Application Custom Resources, allowing tenants with Application creation permissions on the hub cluster to target arbitrary managed spoke clusters. This flaw enables attackers to force ArgoCD on spoke clusters to synchronize attacker-controlled manifests, potentially leading to arbitrary code execution or privilege escalation on those clusters.

A flaw was found in the multicloud-integrations component. The Application propagation controller processes the `ocm-managed-cluster` annotation from an Application Custom Resource (CR) without proper validation. A tenant with permissions to create Applications on the hub cluster can exploit this to target arbitrary managed clusters. This can force ArgoCD on the spoke clusters to synchronize attacker-controlled manifests, leading to arbitrary code execution or privilege escalation on those clusters.
