CVE-2026-84314 Details
Description
Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, the POST /api/users/:id user-management endpoint permits an authenticated user to change another user's password without passing RequireSecureSession, even though the self-service password-change path requires that step-up. An attacker with an authenticated account can change the initial administrator's password, invalidate existing administrator tokens, and then authenticate as the administrator. This issue is fixed in version 2.4.1.
A vulnerability in Nginx UI's user management API endpoint prior to version 2.4.1 allows authenticated users to change passwords of other users, including administrators, without proper session security verification. This flaw could lead to unauthorized access and account takeover.
Users should update to Nginx UI version 2.4.1 or later, where this vulnerability has been fixed.
