Gradio makes the `/file` secure against file traversal and server-side request forgery attacks

Older versions of gradio contained a vulnerability in the /file route which made them susceptible to file traversal attacks in which an attacker could access arbitrary files on a machine running a Gradio app with a public URL (e.g. if the demo was created with share=True, or on Hugging Face Spaces) if they knew the path of files to look for.

This was not possible through regular URLs passed into a browser, but it was possible through the use of programmatic tools such as curl with the --pass-as-is flag.

Furthermore, the /file route in Gradio apps also contained a vulnerability that made it possible to use it for SSRF attacks.

Both of these vulnerabilities have been fixed in gradio==4.11.0
