      "value": "The nexent v1.7.5.2 backend service contains an unauthorized arbitrary storage file deletion vulnerability in its file management API. The DELETE /storage/{object_name:path} endpoint lacks authentication, authorization, and input validation mechanisms. Unauthenticated remote attackers can send crafted requests with a user-controlled object_name path parameter to delete arbitrary files from the underlying MinIO storage system. Successful exploitation leads to data loss and denial of service."

      "value": "El servicio de backend nexent v1.7.5.2 contiene una vulnerabilidad de eliminación arbitraria de archivos de almacenamiento no autorizada en su API de gestión de archivos. El endpoint DELETE /storage/{object_name:path} carece de mecanismos de autenticación, autorización y validación de entrada. Atacantes remotos no autenticados pueden enviar solicitudes manipuladas con un parámetro de ruta object_name controlado por el usuario para eliminar archivos arbitrarios del sistema de almacenamiento MinIO subyacente. La explotación exitosa conduce a la pérdida de datos y a la denegación de servicio."
