CVE-2026-112951 · ApostropheCMS: Color field validation bypass allows stored XSS via HTML appended after rgb()/hsl() prefix
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, the color field accepts trailing content after a valid rgb() or hsl() prefix because its TinyColor validation does not require the entire value to match a color. An authenticated user with edit rights can store arbitrary HTML after a valid color prefix. When the stored value is rendered, the payload executes, resulting in stored XSS. This issue is fixed in version 4.34.0.
