      "value": "The nexent v1.7.5.2 backend service contains an unauthorized arbitrary file deletion vulnerability in its ElasticSearch service interface. The DELETE /{index_name}/documents endpoint lacks proper authentication and authorization controls and does not validate the user-supplied path_or_url parameter. This allows unauthenticated remote attackers to send crafted requests that trigger the deletion of arbitrary documents from ElasticSearch indices and corresponding files from the MinIO storage system. Successful exploitation leads to data destruction and denial of service."

      "value": "El servicio de backend nexent v1.7.5.2 contiene una vulnerabilidad de eliminación arbitraria de archivos no autorizada en su interfaz de servicio de ElasticSearch. El endpoint DELETE /{index_name}/documents carece de controles adecuados de autenticación y autorización y no valida el parámetro path_or_url proporcionado por el usuario. Esto permite a atacantes remotos no autenticados enviar solicitudes manipuladas que desencadenan la eliminación de documentos arbitrarios de índices de ElasticSearch y archivos correspondientes del sistema de almacenamiento MinIO. La explotación exitosa conduce a la destrucción de datos y denegación de servicio."
