Technical details
The In and NotIn operators in Kyverno perform an unchecked type assertion on JMESPath-evaluated arrays, assuming all elements are strings. When JMESPath returns arrays containing integers, booleans, or mixed types (decoded as []interface{}), the assertion panics. An attacker with permission to submit resources can trigger this panic during policy evaluation, causing the admission controller to crash.
