"The version of Gradio installed on the remote host is prior to 4.19.2. It is, therefore, affected by a
Cross-Site Request Forgery (CSRF) vulnerability in gradio-app/gradio which allows attackers to upload multiple
large files to a victim's system if they are running Gradio locally. By crafting a malicious HTML page that
triggers an unauthorized file upload to the victim's server, an attacker can deplete the system's disk space,
potentially leading to a denial of service. This issue affects the file upload functionality as implemented in
gradio/routes.py.

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