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.
