Name of the Vulnerable Software and Affected Versions Kyverno versions prior to 1.17.2

Description A flaw in the ConfigMap context loader allows for cross-namespace privilege escalation. The configMap.namespace field lacks validation, enabling a namespace administrator to read ConfigMaps from any namespace by leveraging Kyverno's privileged service account. This results in a complete Role-Based Access Control (RBAC) bypass in multi-tenant Kubernetes clusters.

Recommendations Update to version 1.17.2.
