Miggo AIRoot Cause Analysis

The vulnerability stems from improper cycle detection in Kustomization file processing. The reconciliation loop (KustomizationReconciler.reconcile) and resource loader (loader.Load) are core components that process user-provided kustomization.yaml files. The lack of cycle checks in these functions allowed recursive references to cause endless loops. The CWE-674 (Uncontrolled Recursion) alignment and the patched 'blocking references' behavior described in advisories strongly implicate these functions. The high confidence comes from the architectural role of these functions and the explicit mention of path/dependency handling fixes in the patch notes.
