Exploitation Conditions

Victim application must use gr.load() to dynamically load a Gradio Space from attacker-controlled source. No authentication required for initial Space hosting or gr.load() invocation against default Gradio configurations.

Impact

CVSS 8.2 (HIGH). Attack vector: Network. Complexity: Low. Privileges required: None. User interaction: None. Exploitable via remote/network.

Exploit ScenarioDerived

A remote attacker could exploit this vulnerability to make arbitrary HTTP requests from a victim's server by hosting a malicious Gradi.

AnalysisAIv1 – Mar 12, 2026

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.

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.

Executive ViewAI

Why It Matters

Gradio versions prior to 6.6.0 contain a critical Server-Side Request Forgery vulnerability that could allow attackers to compromise internal systems and data by exploiting malicious Gradio applications. Organizations using Gradio in production environments face immediate risk of unauthorized access to internal resources, APIs, and sensitive data.

Business Impact: High
Compensating Controls

Implement Web Application Firewall (WAF) rules to monitor and block suspicious outbound requests from Gradio instances; restrict network access using firewall rules to limit outbound connections to only necessary internal and external services; disable or isolate Gradio Space functionality if not operationally required; run Gradio in containerized environments with strict network policies; monitor and log all HTTP requests originating from Gradio servers; consider disabling user-uploaded Gradio applications until patch is available.
