CVE-2026-71468

Acm-search-v2-api-rhel9: search-v2-api: cross-user bearer-token reuse via global federation-config cache

Published Aug 11, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
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.

Remediation

Vendor Workaround

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.
