"The remote host is affected by a vulnerability.");
  script_set_attribute(attribute:"description", value:
"The version of Gradio installed on the remote host is prior to 4.19.2. It is, therefore, affected by a
local file inclusion vulnerability due to improper validation of user-supplied input in the UploadButton 
component. Attackers can exploit this vulnerability to read arbitrary files on the filesystem, such as 
private SSH keys, by manipulating the file path in the request to the `/queue/join` endpoint. This issue 
could potentially lead to remote code execution. The vulnerability is present in the handling of file 
upload paths, allowing attackers to redirect file uploads to unintended locations on the server.

  Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.");
