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\u0027s name pattern (e.g., \u0027*ingress*\u0027). This can be used to circumvent policies such as one blocking hostPath volumes. Fixed in v1.13.0."
