Title: TYPO3 CMS de TYPO3, Description: Usuarios de backend con acceso de escritura a la tabla de la base de datos form_definition pudieron crear, actualizar o eliminar directamente registros de definición de formulario a través de DataHandler, eludiendo la validación de persistencia y las comprobaciones de permisos del Framework de Formularios. Esto permitió inyectar configuraciones de formulario arbitrarias, reactivando vectores de ataque abordados originalmente en TYPO3-CORE-SA-2018-003, incluyendo inyección SQL y escalada de privilegios. Este problema afecta a las versiones 14.0.0-14.3.3 de TYPO3 CMS.

Backend users with write access to the form_definition database table were able to directly create, update, or delete form definition records via DataHandler, bypassing the Form Framework's persistence validation and permission checks. This allowed injecting arbitrary form configurations, re-enabling attack vectors originally addressed in TYPO3-CORE-SA-2018-003, including SQL injection and privilege escalation. This issue affects TYPO3 CMS versions 14.0.0-14.3.3.
