A fix is available — apply it.

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.
