CVE-2023-29018

Cluster privilege escalation via unrestricted role-binding updates

Published Apr 14, 2023 · Updated Feb 6, 2025

Privilege escalation in OpenFeature Operator before 0.2.32 allows local users with node code execution to gain service-account privileges. The controller-manager ClusterRole permits get, list, watch, and update on every ClusterRoleBinding instead of limiting updates to its own binding. Code execution on a Kubernetes node is required; abused permissions expose secrets and permit cluster-state changes that cause denial of service.
