Lobe Chat is a chatbot framework that supports speech synthesis, multimodal, and extensible Function Call plugin system. Prior to 0.150.6, lobe-chat had an unauthorized Server-Side Request Forgery vulnerability in the /api/proxy endpoint. An attacker can construct malicious requests to cause Server-Side Request Forgery without logging in, attack intranet services, and leak sensitive information.
Lobe Chat is an open-source artificial intelligence chat framework. Prior to version 1.19.13, server-side request forgery protection implemented in `src/app/api/proxy/route.ts` does not consider redirect and could be bypassed when attacker provides an external malicious URL which redirects to internal resources like a private network or loopback address. Version 1.19.13 contains an improved fix for the issue.
