gradio Server-Side Request Forgery vulnerability

  • Disclosed: 27.03.2024
  • Updated: 11.10.2026 15:17

An SSRF vulnerability exists in the gradio-app/gradio due to insufficient validation of user-supplied URLs in the /proxy route. Attackers can exploit this vulnerability by manipulating the self.replica_urls set through the X-Direct-Url header in requests to the / and /config routes, allowing the addition of arbitrary URLs for proxying. This flaw enables unauthorized proxying of requests and potential access to internal endpoints within the Hugging Face space. The issue arises from the application's inadequate checking of safe URLs in the build_proxy_request function.
