CVE-2026-71468: Red Hat Advanced Cluster Management For Kubernetes 2.11

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
