This flaw enables an attacker with specific permissions to gain full control of the application by leveraging the ability to set arbitrary credentials for the newly created SuperAdmin account.

Original NVD Description

phpMyFAQ before 4.1.5 contains a privilege escalation vulnerability in the user/add API endpoint that allows non-SuperAdmin administrators to create SuperAdmin accounts. A delegated administrator with USER_ADD/EDIT/DELETE permissions can call POST /admin/api/user/add with isSuperAdmin: true and attacker-chosen credentials to create a SuperAdmin account, then authenticate as that account to achieve full instance takeover.
