This CVE record is not being prioritized for NVD enrichment efforts due to resource or other concerns.
Description
The path allowance check in GeneralUtility::isAllowedAbsPath() performed a plain string prefix comparison without requiring a directory separator boundary, causing a path like /var/www/html-other/secret.yaml to be incorrectly accepted as valid when the project root was /var/www/html. Administrator users with access to the File Abstraction Layer were able to create new file storage definitions pointing to directories outside the project root, bypassing this path check. This issue affects TYPO3 CMS versions before 10.4.57, 11.0.0-11.5.50, 12.0.0-12.4.45, 13.0.0-13.4.30 and 14.0.0-14.3.2.

Title: TYPO3 CMS de TYPO3, Description: La comprobación de permiso de ruta en GeneralUtility::isAllowedAbsPath() realizó una comparación de prefijo de cadena simple sin requerir un límite de separador de directorio, lo que provocó que una ruta como /var/www/html-other/secret.yaml fuera aceptada incorrectamente como válida cuando la raíz del proyecto era /var/www/html. Los usuarios administradores con acceso a la Capa de Abstracción de Archivos pudieron crear nuevas definiciones de almacenamiento de archivos apuntando a directorios fuera de la raíz del proyecto, eludiendo esta comprobación de ruta. Este problema afecta a las versiones de TYPO3 CMS anteriores a 10.4.57, 11.0.0-11.5.51, 12.0.0-12.4.46, 13.0.0-13.4.31 y 14.0.0-14.3.3.
