      "value": "Craft CMS is a content management system (CMS). In versions 5.0.0-RC1 and above prior to 5.9.21, the EntriesController::actionMoveToSection() endpoint gates the destination section only by viewEntries:$section->uid rather than requiring saveEntries permission (the source entry is separately checked via Entry::canMove()). As a result, a low-privileged authenticated control-panel user who can move an entry out of its current section can call moveEntryToSection() to rewrite the entry's sectionId and save it into a section where they have read access but no write access. This breaks the section-level authorization model, letting a user with limited permissions inject content into a protected section and interfere with editorial boundaries, approval workflows, and section-specific business logic. This issue has been fixed in version 5.9.21."

      "value": "Craft CMS es un sistema de gestión de contenido (CMS). En las versiones 5.0.0-RC1 y superiores anteriores a la 5.9.21, el endpoint EntriesController::actionMoveToSection() restringe la sección de destino solo por viewEntries:$section  ->  uid en lugar de requerir el permiso saveEntries (la entrada de origen se verifica por separado a través de Entry::canMove()). Como resultado, un usuario autenticado del panel de control con privilegios bajos que puede mover una entrada fuera de su sección actual puede llamar a moveEntryToSection() para reescribir el sectionId de la entrada y guardarla en una sección donde tiene acceso de lectura pero no de escritura. Esto rompe el modelo de autorización a nivel de sección, permitiendo que un usuario con permisos limitados inyecte contenido en una sección protegida e interfiera con los límites editoriales, los flujos de trabajo de aprobación y la lógica de negocio específica de la sección. Este problema ha sido solucionado en la versión 5.9.21."
