AI-suggested
Currently, Red Hat states that no mitigation or fix is available that meets their criteria for ease of use, applicability, and stability. Users should monitor the Red Hat advisory for updates. Until an official fix or mitigation is released, restricting Application creation permissions to trusted users and minimizing the attack surface are recommended as interim risk reduction measures.
Description
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.
