Summary

A flaw was found in the Ansible aap-gateway. Concurrent requests handled by the gateway grpc service can result in concurrency issues due to race condition requests against the proxy.

This issue potentially allows a less privileged user to obtain the JWT of a greater privileged user, enabling the server to be jeopardized. A user session or confidential data might be vulnerable.

Red Hat has evaluated this vulnerability. This issue only affects versions AAP 2.5 GA and onwards.

Red Hat severity: Important — CVSS 8.1 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N). Weakness: CWE-362.

Affected Red Hat products: Red Hat Ansible Automation Platform 2.5 for RHEL 8; Red Hat Ansible Automation Platform 2.5 for RHEL 9. Red Hat fixing advisory: RHSA-2025:1954.

Is CVE-2025-1801 exploited?

No exploitation is reported in the sources VulniPulse tracks: CVE-2025-1801 is not in the CISA KEV catalog (checked ) and this advisory does not report exploitation. That is not proof the vulnerability cannot be exploited.

Mitigation checklist

Recommended fix / mitigation
  • Follow the mitigation steps to avoid the flaw from happening. It is recommended to update the product after the fix is available. 1) set GRPC_SERVER_MAX_THREADS_PER_PROCESS = 1 This mitigates problems going FORWARD for the issue because there is only one thread using the ExternalAuth() object instantiated by the parent process. This eliminates the thread safety risk as the worker only processes one request at a time. 2) It is possible that at any time since the install/upgrade of AAP 2.5, that long lived Oauth tokens created in the components with the endpoints could implicate long term access to a different user's identity/privileges. Requests made with these tokens will appear to be from the user for which they were created and are indistinguishable from “valid” tokens that were created by the correct user: /api/controller/v2/tokens/ /api/controller/v2/applications/<id>/tokens/ /api/galaxy/v3/auth/token/ /api/controller/o/token/ Because it is likely not feasible to back trace every request that could have generated a token to its original request in the GRPC server, the most conservative and safe path to mitigate this risk would be to invalidate/revoke all existing oauth tokens in the components (hub, controller, eda).
