## Technical details

The Auth Guard fails to call exit() or die() after sending a Location redirect header when $_SESSION['user_id'] is empty, allowing execution to continue past the authentication check. An attacker can manipulate the user_id parameter to reach protected admin pages and execute sensitive operations (user deletion, password changes, SQL queries) without proper authentication. A network-based remote attack requires no prior authentication or user interaction.
