The `submariner-k8s-broker-cluster` Role, which is assigned to joined clusters, possesses excessive permissions. This allows a compromised cluster to alter network configurations, specifically by overwriting other clusters' endpoint information. Consequently, an attacker can redirect inter-cluster tunnel traffic, enabling a Man-in-the-Middle (MITM) attack across the entire cluster mesh.","state":0,"publishedAt":"2026-08-18T17:32:00.879+00:00","modifiedAt":"2026-10-19T17:01:55.013+00:00","affected":[{"ecosystem":"https://catalog.redhat.com/software/containers/","name":"rhacm2/submariner-addon-rhel9","ranges":[],"versions":[],"rawVersionEvidence":"{\n
