Summary

In text-generation-inference up to version 3.3.7, a server-side request forgery (SSRF) vulnerability exists in the OpenAI-compatible multimodal chat completions endpoint. An unauthenticated network attacker can force the server to issue arbitrary HTTP GET requests by supplying a crafted image_url value in chat message content.

Risk Assessment

An attacker can scan internal ports, access internal services, and steal credentials from cloud instance metadata endpoints, leading to confidentiality and integrity breaches.

Recommendation

Immediately update text-generation-inference to a version newer than 3.3.7 where this vulnerability is fixed. Until then, restrict access to the multimodal chat completions endpoint and implement validation of image URLs.

Original NVD description (English source)

text-generation-inference through 3.3.7 contains a server-side request forgery (SSRF) vulnerability in the OpenAI-compatible multimodal chat completions endpoint that allows unauthenticated network attackers to coerce the server into issuing arbitrary HTTP GET requests by supplying a crafted image_url value in chat message content. The fetch_image function in router/src/validation.rs performs no validation of private, loopback, link-local, or cloud metadata target addresses, and the reqwest HTTP client follows redirects by default, enabling attackers to bypass scheme checks via redirect chains to reach internal services and cloud instance-metadata endpoints for internal port scanning and credential theft.
