| Description | The affected component is `includes/process.php`, the central AJAX backend for registration, login, category/brand/product CRUD, record listing, deletion, updates, and order creation. The file includes `constants.php` (which starts a session) but never checks `$_SESSION["userid"]` before performing privileged operations:
```php
if (isset($_POST["category_name"]) AND isset($_POST["parent_cat"])) {
$obj = new DBOperation();
$result = $obj->addCategory($_POST["parent_cat"],$_POST["category_name"]);
echo $result;
exit();
}
```
An unauthenticated remote attacker can create, read, update, and delete inventory data and place orders solely by posting the expected form fields. |
