Money Manager EX WebApp (web-money-manager-ex) 1.2.2 is vulnerable to Incorrect Access Control. The `redirect_if_not_loggedin` function in `functions_security.php` fails to terminate script execution after redirecting unauthenticated users. This flaw allows an unauthenticated attacker to upload arbitrary files, potentially leading to Remote Code Execution.
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
