PROBLEM TYPE

### 1\. Unauthorized Data Deletion

This vulnerability is found in the **Online Student Clearance System** project.

#### ???? Vulnerable File Location

`Admin/delete-fee.php` (Lines 6-10)

#### ???? Vulnerable Code

```php
error_reporting(0);
include('../connect.php');
include('../connect2.php');

$id= $_GET['id'];
$sql = "DELETE FROM fee WHERE ID=?";
$stmt= $dbh->prepare($sql);
$stmt->execute([$id]);

header("Location: add-fee.php");
```

#### ???? Description

The script `Admin/delete-fee.php` executes a `DELETE` query on the `fee` table based on the ID provided via the **`GET`** parameter `id`.

This is a **Broken Access Control** vulnerability, as the script **lacks any authorization checks** (e.g., verifying if the user is logged in or has administrator privileges). Any user, including unauthenticated users, can execute this script by directly accessing the URL (e.g., `/Admin/delete-fee.php?id=123`), leading to unauthorized data deletion.

#### ????️ Suggested Mitigation

Implement a strict **authorization and authentication check** at the beginning of the script. Ensure that only users with the appropriate administrative role are permitted to execute the deletion operation.
