Is this vulnerability remotely exploitable?

Yes. An attacker can exploit it remotely by controlling a Gradio Space that the victim server loads via `gr.load()`. Once the victim loads that Space, the attacker can trigger SSRF through the trusted `proxy_url` configuration.

What level of access does an attacker need?

The attacker must be able to host or modify a Gradio Space that the victim chooses to load. They do not need direct access to the victim's infrastructure or internal network; exploitation is mediated through the Space configuration and the victim's use of `gr.load()`.

What is the safest general fix pattern?

The safest pattern is to stop treating external Spaces as a source of trusted network configuration. Enforce strict validation on any URL or proxy-related configuration, avoid dynamically extending allowlists based on remote data, and constrain outbound requests to a small, predefined set of destinations.
