Root Cause Analysis
The vulnerability arises because Kyverno's PolicyException handling did not restrict exceptions to specific namespaces. Functions responsible for processing or validating PolicyExceptions (e.g., reconciliation logic and policy exception checks) would need to enforce namespace constraints to prevent unauthorized overrides. The confidence is medium because the exact code flow isn't visible, but the described vulnerability mechanics strongly implicate these components. The patched version (1.13.0) likely introduced namespace-scoping logic in these areas.
