Kyverno before 1.19.2 contains a missing authorization vulnerability that allows namespaced Policy authors to read resources in other namespaces by templating generate.clone or cloneList namespace values. Attackers can annotate a triggering ConfigMap so the background-controller copies a victim namespace's sensitive ConfigMap into the attacker's namespace, enabling cross-tenant data disclosure.
