CVE-2024-47084
Gradios's CORS origin validation is not performed when the request has a cookie
Impact
### Impact **What kind of vulnerability is it? Who is impacted?** This vulnerability is related to **CORS origin validation**, where the Gradio server fails to validate the request origin when a cookie is present. This allows an attacker’s website to make unauthorized requests to a local Gradio server. Potentially, attackers can upload files, steal authentication tokens, and access user data if the victim visits a malicious website while logged into Gradio. This impacts users who have deployed Gradio locally and use basic authentication. ### Patches Yes, please upgrade to `gradio>=4.44` to address this issue. ### Workarounds **Is there a way for users to fix or remediate the vulnerability without upgrading?** As a workaround, users can manually enforce stricter CORS origin validation by modifying the `CustomCORSMiddleware` class in their local Gradio server code. Specifically, they can bypass the condition that skips CORS validation for requests containing cookies to prevent potential exploitation.
