CVE-2026-63670 · ApostropheCMS: Mutation-XSS / allowedTags bypass via literal `</textarea/>` solidus close
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
ApostropheCMS is an open-source Node.js content management system. Prior to 2.17.6, sanitizeHtml() can pass disallowed executable markup through packages/sanitize-html/index.js when textarea or xmp is included in allowedTags because a literal solidus after the raw-text end-tag name is treated as text by htmlparser2 and the ontext handler emits that content without escaping, while a browser parses the following img onerror markup as active HTML. This issue is fixed in version 2.17.6.
