NextChat, also known as ChatGPT-Next-Web, is a cross-platform chat user interface for use with ChatGPT. Versions 2.11.2 and prior are vulnerable to server-side request forgery and cross-site scripting. This vulnerability enables read access to internal HTTP endpoints but also write access using HTTP POST, PUT, and other methods. Attackers can also use this vulnerability to mask their source IP by forwarding malicious traffic intended for other Internet targets through these open proxies. As of time of publication, no patch is available, but other mitigation strategies are available. Users may avoid exposing the application to the public internet or, if exposing the application to the internet, ensure it is an isolated network with no access to any other internal resources.

NextChat (formerly ChatGPT-Next-Web) versions prior to 2.11.3 are vulnerable to Server-Side Request Forgery (SSRF) and Cross-Site Scripting attacks, allowing remote and unauthenticated attacker to make the vulnerable instance issue arbitrary requests on both external or internal assets through the '/api/cors' endpoint or to execute JavaScript in the application users browsers context.

The remote host contains a torchserve version that is prior to 2.11.3. It is, therefore, affected by a Server Side Request Forgery vulnerability in the api/cors endpoint.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
