DescriptionCVE.org
A flaw was found in the Submariner operator. 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.
