Red Hat OpenShift GitOps multicloud-integrations: OCM Annotation Validation Flaw
CVE-2026-72526 Published on August 12, 2026
Multicloud-integrations: multicloud-integrations: pull-model propagation allows hub tenant to target arbitrary spoke cluster via unvalidated ocm-managed-cluster annotation
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.

Weakness Type
What is a Confused Deputy Vulnerability?
The product receives a request, message, or directive from an upstream component, but the product does not sufficiently preserve the original source of the request before forwarding the request to an external actor that is outside of the product's control sphere. This causes the product to appear to be the source of the request, leading it to act as a proxy or other intermediary between the upstream component and the external actor.
CVE-2026-72526 has been classified to as a Confused Deputy vulnerability or weakness.
