## Technical details

The vulnerability is an authentication bypass (CWE-306) and privilege escalation (CWE-862, CWE-269) in the saveuser.php endpoint. The vulnerable component fails to enforce server-side authentication or authorization checks before processing account creation requests. An attacker can delete their session cookie or craft a direct request to saveuser.php without an authenticated session, modify the "position" parameter to "admin", and the server will accept the request and create a new administrator account. The root cause is that the application relies on client-side form controls and session validation at the UI level only, not at the backend. There are no confirmed fixes at the time of this advisory; the vulnerability affects version 1.0 and the application is available on SourceCodester.
