Cluster privilege escalation via overbroad cert-controller RBAC
Published Sep 9, 2024 · Updated Sep 9, 2024
Privilege escalation in the cert-controller RBAC for External Secrets Operator before 0.10.2 allows local users to read cluster secrets. The default cert-controller ClusterRole grants its service account cluster-wide secret get/list access and unrestricted webhook patch/update access. Worker-node access exposes that service-account token, enabling secret theft or webhook changes that block Pod creation and updates.
