Technical details
A Server-Side Request Forgery (SSRF) vulnerability exists in Gradio's 'gr.load()' function due to insufficient validation of the 'proxy_url' parameter in remote configuration files. When a Gradio application loads an external Space, the 'proxy_url' provided by the remote config is automatically added to an internal allowlist without verification. An attacker can provide a malicious configuration pointing to internal IP addresses or cloud metadata services (e.g., 169.254.169.254). Because Gradio's built-in '/proxy' route only performs host-based validation against this allowlist, an attacker can then use the victim's server as a reverse proxy to access restricted internal endpoints. This vulnerability is patched in version 6.6.0.
