4.18.0- Upgrade gradio to this version or later
Description
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.
Affected versions
PyPI
| Package | Vulnerable | Fixed in |
|---|---|---|
| gradio | < 4.18.0 |
4.18.0 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
gradio PyPI → 4.18.0
- pip
pip install --upgrade "gradio>=4.18.0"- poetry
poetry add "gradio>=4.18.0"- uv
uv add "gradio>=4.18.0"
