What potential security risks are associated with using Request.Form in PHP?

Using Request.Form in PHP can potentially expose your application to security risks such as SQL injection attacks. To mitigate this risk, it is recommended to use parameterized queries when interacting with a database to prevent malicious input from being executed as SQL commands. 

// Using parameterized queries to prevent SQL injection
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $_POST['username']);
$stmt->execute();
