CVE-2026-28416 Details
Description
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.
A Server-Side Request Forgery (SSRF) vulnerability exists in Gradio versions prior to 6.6.0. This vulnerability 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 the attacker-controlled Space, the harmful 'proxy_url' from the configuration is trusted and added to an allowlist. This enables the attacker to access internal services, cloud metadata endpoints, and private networks through the victim's infrastructure.
Users are advised to update Gradio to version 6.6.0 or later, where this vulnerability has been fixed.
