Medium 6.9
In plain English
A medium-severity security flaw in gradio from gradio-app. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.5% (higher than 45% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official 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.
