  "details": "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 nonTextTags configuration that includes noscript can end its discard region early when htmlparser2 emits an implied ancestor close inside noscript. Because scripting-enabled browsers treat noscript content as raw text while the parser does not model that mode, content intended to remain inert can survive sanitization and render; the issue does not generalize to every default nonTextTags element. This issue is fixed in sanitize-html 2.18.0.",
