DescriptionGitHub Advisory

Gradio is an open-source Python package designed for quick prototyping. Prior to version 6.6.0, a Server-Side Request Forgery (SSRF) vulnerability in Gradio allows an attacker to make arbitrary HTTP requests from a victim's server by hosting a malicious Gradio Space. When a victim application uses gr.load() to load an attacker-controlled Space, the malicious proxy_url from the config is trusted and added to the allowlist, enabling the attacker to access internal services, cloud metadata endpoints, and private networks through the victim's infrastructure. Version 6.6.0 fixes the issue.

AnalysisAI

Server-Side Request Forgery in Gradio prior to version 6.6.0 allows attackers to execute arbitrary HTTP requests through a victim's infrastructure by crafting a malicious Space with a poisoned proxy_url configuration. Applications that load untrusted Gradio Spaces via gr.load() are vulnerable to attacks targeting internal services, cloud metadata endpoints, and private networks. No patch is currently available for affected Python/ML applications.
