CVE-2026-71468 Red Hat CVE debrief

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.

Who should care

Users of acm-search-v2-api-rhel9, administrators of remote managed hub search results, and security teams responsible for monitoring and protecting against unauthorized access should review the CVE record and take necessary actions to protect their systems. This includes verifying cache expiration and user authentication mechanisms, reviewing and updating access controls, and monitoring for suspicious activity. Security teams should also consider implementing compensating controls for exposed systems while remediation is scheduled and verified. Additionally, asset inventory and vulnerability management teams should be aware of the potential impact on their systems and plan accordingly. The affected product deployments should be identified, and owners should be assigned for follow-up. The official advisory or CVE record should be reviewed to validate affected scope, severity, and vendor guidance. Exceptions should be tracked, and remediated assets should be retested and documented before closing the item. Monitoring, detection, and logs should be checked for exposed assets that need extra review. Rollback/change windows and source tracking should also be considered as part of the remediation plan. The CVE record and NVD entry provide limited information, and defenders should verify the affected scope and severity with the vendor. The vulnerability class is related to improper reuse of bearer tokens, and the likely operational impact is information disclosure. The source-confidence limits are based on the CVE record and NVD entry, and review context is necessary to understand the vulnerability and its impact. Compensating controls, such as monitoring and asset inventory, should be reviewed and updated to address the vulnerability. The defensive priority is to prevent unauthorized access to remote managed hub search results and to protect against information disclosure. The recommended actions include verifying cache expiration and user authentication mechanisms, reviewing and updating access controls, monitoring for suspicious activity, and implementing compensating controls. The debrief provides an executive overview of the vulnerability, its impact, and the need

Technical summary

The `getFederationConfig` function in acm-search-v2-api-rhel9 improperly reuses a user's bearer token for all subsequent federated requests until the cache expires.
