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.
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.
