Short explanation

LLMGateway through version 1.20.0 contains a blind server-side request forgery vulnerability that allows API key holders to reach internal hosts via the video-generation callback_url extension.

Why does it matter?

This flaw allows authenticated attackers to dispatch webhook POST requests from the worker network to internal services and cloud metadata endpoints.

What should be done?

Follow vendor advisories
Implement proper validation for webhook targets
Strengthen internal network access controls
