RedHat ACM Search API RHEL9: Improper Bearer Token Reuse in Federation Cache
CVE-2026-71468 Published on August 11, 2026

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