## Technical details

A path traversal flaw in admin/delete.php fails to sanitize the image_name GET parameter before passing it to PHP's unlink() function. An attacker can use sequences like ../../config/constants.php to traverse outside the intended upload directory and delete application files. The vulnerability affects multiple admin endpoints (delete_category.php, update_food.php, update_category.php) with the same pattern and requires no authentication.
