Doc Text:
A flaw was found in Kyverno. An authorization bypass vulnerability in the Generation Handler allows authenticated users with resource creation or update privileges to trigger automated generation policies by spoofing internal system labels. By applying crafted labels to resources such as configuration maps, an attacker can clone sensitive secrets from restricted namespaces into their own namespace, resulting in unauthorized information disclosure.

Description OSIDB Bzimport 2026-11-05 22:13:00 UTC 
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.
