A Server-Side Request Forgery (SSRF) vulnerability exists in the upload processing interface of gaizhenbiao/ChuanhuChatGPT versions <= ChuanhuChatGPT-20240410-git.zip. This vulnerability allows attackers to send crafted requests from the vulnerable server to internal or external resources, potentially bypassing security controls and accessing sensitive data.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
