Submit #897074: inventory-management-system v1.0.0 SQL Injection

rabindralamsal/inventory-management-system has a SQL Injection leading to Authentication Bypass Vulnerability. The login logic in `index.php` directly concatenates user-controlled `username` and `password` values into SQL statements without parameterized queries or escaping.
The login logic in `index.php` directly concatenates user-controlled `username` and `password` values into SQL statements without parameterized queries or escaping.

Relevant code pattern:

```php
$username = $_POST['username'];
$password = $_POST['password'];

$sql = "SELECT * FROM users WHERE username = '$username'";
$result = $connect->query($sql);

$password = md5($password);
$mainSql = "SELECT * FROM users WHERE username = '$username' AND password = '$password'";
$mainResult = $connect->query($mainSql);
```

The `username` parameter is not filtered in this process, resulting in SQL injection vulnerabilities.
