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

When the `getFederationConfig` function refreshes its cache, it improperly reuses a user\u0027s 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."
