CVE-2024-47084 Information

Description

Gradio is an open-source Python package designed for quick prototyping. 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. Users are advised to upgrade to gradio>4.44 to address this issue. 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.
