What are potential security risks associated with passing sensitive data like passwords through cURL in PHP?

Passing sensitive data like passwords through cURL in PHP can pose a security risk because the data is transmitted in plain text, making it vulnerable to interception by malicious actors. To mitigate this risk, it is recommended to use HTTPS for secure data transmission. This ensures that the data is encrypted during transit, making it much more difficult for unauthorized parties to access. 

$url = 'https://example.com/api';
$data = array(
    'username' => 'my_username',
    'password' => 'my_password'
);

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // Disables SSL verification (for testing purposes only)
$response = curl_exec($ch);

if($response === false) {
    echo 'Error: ' . curl_error($ch);
} else {
    echo 'Response: ' . $response;
}

curl_close($ch);
