Mitigation checklist
- To mitigate this issue, ensure that the `FEATURE_FEDERATED_SEARCH` is not enabled if federated search functionality is not required. This feature is disabled by default in Red Hat Advanced Cluster Management for Kubernetes. If `FEATURE_FEDERATED_SEARCH` is enabled, consider disabling it to prevent unauthorized cross-user data access. Disabling this feature will impact the ability to perform federated searches across managed hubs.
