Insufficient safeguards against malicious API response values allow authenticated attackers with 'Sys.Audit' or 'VM.Monitor' privileges to download arbitrary host files via the API.\nWhen handling the result from a request handler before returning it to the user, the handle_api2_request function will check for the \u2018download\u2019 or \u2018data\u2019->\u2019download\u2019 objects inside the request handler call response object.
