Mitigation checklist

Recommended fix / mitigation

Restrict `create`, `update`, and `patch` permissions for Console custom resources to trusted administrators only. Where supported, apply a NetworkPolicy to restrict Console API egress to approved Kafka broker endpoints. These controls reduce exposure to the reported ServiceAccount-credential disclosure path but do not replace the permanent fix, which is to filter security-sensitive Kafka client properties. Upgrade to a release containing the permanent fix when available.
