gradio is vulnerable to Open Redirect
49
Medium Risk
This Affects:
gradioTL;DR
The /gradio_api/file= endpoint accepts any HTTP or HTTPS URL as a path parameter and immediately returns a redirect to that URL without validation. Untrusted URLs can redirect users to arbitrary external sites, and because the client library follows redirects, a crafted file response can drive requests to internal endpoints such as cloud metadata services. This enables client-side server-side request forgery that can retrieve sensitive credentials such as instance role credentials. The fix restricts redirects to an allow-list and serves the URL through a request-forgery-safe proxy that validates the resolved host.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your deployment serves or renders externally influenced FileData URLs through the /gradio_api/file= endpoint (for example a client or browser that follows the endpoint's redirects).
Background info
gradio is vulnerable to Open Redirect in versions 0.0.1 - 6.19.0.
How to fix this
