Kyverno before v1.13.0 Policy Bypass via Multiple Exceptions
Kyverno versions v1.9.0 through v1.12.7 contain a policy exception handling flaw. When a policy in enforce mode is combined with two PolicyExceptions, the less restrictive exception takes precedence, allowing an attacker to bypass the policy by crafting a resource name that matches the second exception's name pattern (e.g., 'ingress'). This can be used to circumvent policies such as one blocking hostPath volumes. Fixed in v1.13.0.
