LLMGateway through 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. Attackers can supply loopback, private, or cloud-metadata URLs that deliverWebhook POSTs to without the assertSafeWebhookTarget check, reaching internal services from the worker's network.
