CVE-2026-71468 (GCVE-0-2026-71468)

Vulnerability from cvelistv5 – Published: 2026-08-11 19:24 – Updated: 2026-08-12 16:58

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.

Severity

GHSA-WG82-W434-QWGQ

Vulnerability from github – Published: 2026-08-11 21:33 – Updated: 2026-08-11 21:33

Details

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.",
