Name of the Vulnerable Software and Affected Versions Kyverno versions prior to 1.13.0

Description A kyverno ClusterPolicy can be overridden by the creation of a PolicyException in a random namespace. By design, PolicyExceptions are consumed from any namespace, which may allow users with privileges to non-kyverno namespaces to create exceptions. Administrators may not recognize this potential bypass.

Recommendations For versions prior to 1.13.0, update to version 1.13.0 to fix the vulnerability. As a temporary workaround, consider restricting the creation of PolicyException objects to authorized namespaces until the update is applied. Restrict access to the PolicyException object to minimize the risk of exploitation. Avoid using the PolicyException object in non-kyverno namespaces until the issue is resolved.
