      "value": "Apache Kyuubi REST batch multipart upload handling uses the client-supplied multipart filename when creating a temporary uploaded resource. A remote attacker who can access the REST batch upload endpoint can provide path traversal sequences in the filename and cause the Kyuubi server process to write controlled content outside the intended upload directory, subject to filesystem permissions.\n\n\nThis issue affects Apache Kyuubi: from 1.7.0 through 1.11.1.\n\nUsers are recommended to upgrade to version 1.12.0, which fixes the issue."

Un atacante remoto que puede acceder al punto final de carga por lotes REST puede proporcionar secuencias de salto de ruta en el nombre de archivo y hacer que el proceso del servidor Kyuubi escriba contenido controlado fuera del directorio de carga previsto, sujeto a los permisos del sistema de archivos.\n\nEste problema afecta a Apache Kyuubi: desde la 1.7.0 hasta la 1.11.1.\n\nSe recomienda a los usuarios actualizar a la versión 1.12.0, que corrige el problema."
