CVE ID :CVE-2026-72526
Published : Aug. 12, 2026, 2:16 a.m. | 1 hour, 12 minutes ago
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.
Severity: 9.9 | CRITICAL
