How can one propose code changes to a PHP framework through a Pull Request on GitHub?

Issue: The current implementation of the authentication system in the PHP framework is vulnerable to SQL injection attacks. To fix this issue, we need to use parameterized queries to prevent malicious input from being executed as SQL commands. Code snippet: 

// Original code
$username = $_POST['username'];
$password = $_POST['password'];

$query = "SELECT * FROM users WHERE username = '$username' AND password = '$password'";
$result = $pdo->query($query);

// Fixed code using parameterized queries
$username = $_POST['username'];
$password = $_POST['password'];

$query = "SELECT * FROM users WHERE username = :username AND password = :password";
$statement = $pdo->prepare($query);
$statement->bindParam(':username', $username);
$statement->bindParam(':password', $password);
$statement->execute();
$result = $statement->fetchAll();
