Volcano is a Kubernetes-native batch scheduling system. Prior to versions 1.11.2, 1.10.2, 1.9.1, 1.11.0-network-topology-preview.3, and 1.12.0-alpha.2, attacker compromise of either the Elastic service or the extender plugin can cause denial of service of the scheduler. This is a privilege escalation, because Volcano users may run their Elastic service and extender plugins in separate pods or nodes from the scheduler. In the Kubernetes security model, node isolation is a security boundary, and as such an attacker is able to cross that boundary in Volcano's case if they have compromised either
