A flaw was found in acm-search-v2-api-rhel9. When the getFederationConfig function refreshes its cache, it improperly reuses a user's bearer token for all subsequent federated requests until the cache expires. This allows other authenticated users to gain unauthorized access to remote managed hub search results, leading to information disclosure.
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.
