Description

Kyverno before 1.19.2 contains an authorization bypass vulnerability in the Generation Handler that allows users with create/update permissions to trigger synchronized generate policies by spoofing internal generate.kyverno.io labels. Attackers can label a ConfigMap as managed-by kyverno with crafted policy, rule, and trigger labels to clone sensitive Secrets from restricted namespaces into their own namespace.
