ApostropheCMS is an open-source Node.js content management system, and sanitize-html provides a simple HTML sanitizer with a clear API. Prior to sanitize-html 2.18.0, a non-default configuration that allows meta refresh elements and their http-equiv and content attributes can retain unsafe script or redirect destinations embedded in the refresh content value. This issue is fixed in sanitize-html 2.18.0.
