The WP Contact Form III 1.4.1 WordPress plugin by ‘KristinKWangen’ is vulnerable to multiple cross site scripting attacks.

Note to developers, this does not stop script injection attacks:

From wp-contactform.php line 105:

$_POST['wpcf_your_name'] = stripslashes(trim($_POST['wpcf_your_name']));

Also note that this is not a very good way to die:

From buttonsnap.php line 28:

$selection = isset($_POST['selection']) ? $_POST['selection'] : @$_GET['selection'];
$selection = apply_filters($dispatch, $selection);
die($selection);
