This vulnerability allows for the exposure of a long-lived broker service account (SA) bearer token within the Submariner Custom Resource (CR) specification. An attacker with access to the cluster's etcd database or through `kubectl get` commands could obtain this token. The possession of this token grants full control over the mesh network, enabling unauthorized management of network resources such as endpoints and secrets.","state":0,"publishedAt":"2026-08-18T17:06:00.421+00:00","modifiedAt":"2026-10-19T17:02:14.75+00:00","affected":[{"ecosystem":"https://catalog.redhat.com/software/containers/","name":"rhacm2/subctl-rhel9","ranges":[],"versions":[],"rawVersionEvidence":"{\n
