Summary		(es) Kirby es un sistema de gestión de contenidos de código abierto. Antes de las versiones 4.9.4 y 5.4.4, los sitios y plugins de Kirby que utilizan los campos ’writer’ o ’list’ o que llaman a Dom::sanitize(), Sane::sanitize(), Sane::Html::sanitize(), Sane::Svg::sanitize(), Sane::Xml::sanitize(), Sane::sanitizeFile(), o a file sanitizeContents() con entrada no confiable, permiten que marcado malicioso inyectado como hijos de una etiqueta HTML o XML desconocida pase a través de Dom::sanitize() sin ser correctamente sanitizado, causando cross-site scripting almacenado. Este problema está solucionado en las versiones 4.9.4 y 5.4.4.
