| Doc Text: |
A flaw was found in Kyverno. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by submitting specially crafted resources evaluated by the In and NotIn operators. Because the policy engine fails to properly validate unexpected data types, processing these inputs triggers an unhandled crash. This failure halts Kyverno's policy engine, disrupting cluster admission control and security policy enforcement.
