NewCVE-2025-46342 Â (opens in a new tab)How to fix?
Upgrade github.com/kyverno/kyverno/pkg/utils/engine to version 1.13.5, 1.14.0 or higher.
Overview
Affected versions of this package are vulnerable to Authentication Bypass Using an Alternate Path or Channel due to improper handling of namespace selectors in the GetNamespaceSelectorsFromNamespaceLister() function in labels.go. An attacker can bypass policy rules using malicious requests that omit or manipulate namespace information. If the Kube API Server can be compromised to partially deny service by other means, which notably have not been realistically demonstrated, the SharedIndexInformer cache can fall behind. This forces an error, which rather than being propagated to the endpoint, is returned as an empty label map.
