Prior to 17.4.0, OpenProject's rich text (markdown) rendering pipeline uses Sanitize::Config::RELAXED[:css] for inline style sanitization. This configuration permits essentially all CSS properties in style attributes on permitted HTML elements (figure, img, table, th, tr, td). This allows any authenticated user with write access to formattable text fields (work package descriptions, comments, project descriptions, news) to inject CSS This vulnerability is fixed in 17.4.0."

Antes de la versión 17.4.0, la canalización de renderizado de texto enriquecido (markdown) de OpenProject utiliza Sanitize::Config::RELAXED[:css] para la sanitización de estilos en línea. Esta configuración permite esencialmente todas las propiedades CSS en atributos de estilo en elementos HTML permitidos (figure, img, table, th, tr, td). Esto permite a cualquier usuario autenticado con acceso de escritura a campos de texto formateables (descripciones de paquetes de trabajo, comentarios, descripciones de proyectos, noticias) inyectar CSS. Esta vulnerabilidad se corrige en la versión 17.4.0."
