Detailed vulnerability description
The vulnerability allows a remote user to disclose sensitive information and cause a denial of service.
The vulnerability exists due to server-side request forgery in OpenAI-compatible multimodal image_url fetching when handling crafted image_url values in requests to the OpenAI-compatible endpoints. A remote user can send a specially crafted request containing an attacker-controlled image_url to disclose sensitive information and cause a denial of service.
The issue affects requests processed through POST /v1/chat/completions and POST /v1/completions, and can reach internal or loopback destinations from the server network context.
