CVE-2026-112958 · ApostropheCMS: Stored XSS via Unescaped Widget Style Attribute Serialization
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 4.34.0, a project-defined free-form widget style field can carry an editor-controlled quote into an inline style attribute because the wrapper serializer does not apply HTML-attribute encoding. The quote can terminate the style attribute and inject executable attributes when published content, or an affected draft viewed by a higher-privileged user, is rendered. This issue is fixed in version 4.34.0.
