Description OSIDB Bzimport 2026-11-05 22:16:04 UTC 
Kyverno before 1.19.2 contains a denial-of-service vulnerability in the In and NotIn operators that allows attackers to crash the policy engine via an unchecked type assertion. Attackers can submit resources whose JMESPath-evaluated values yield arrays of integers, booleans, or mixed types, triggering a panic that disrupts admission control and policy enforcement.
