Hello i don't know if this vuln is already out , but i've searched in securityfocus and is not present.

Bug found in load_message.php at line 4:

<?php echo $lang['please_wait']; ?>

Ex: http://localhost/youtube/siteadmin/editor_files/includes/load_message.php?lang[please_wait]=[XSS]

Fix:

<?php echo htmlspecialchars($lang['please_wait']); ?>
