Vendor / product: Kyverno — kyverno
Kyverno before 1.19.2 contains a policy bypass vulnerability in the admissionpolicygenerator controller, which folds PolicyExceptions into generated ValidatingAdmissionPolicies while ignoring the --enablePolicyException, --exceptionNamespace, and policy kind gates. Users with namespaced create rights on PolicyExceptions can inject negated matchConditions into the generated policies to admit violating resources, bypassing cluster-wide enforcement.
