@lobehub/chat Server Side Request Forgery vulnerability
Summary
lobe-chat before 1.19.13 has an unauthorized ssrf vulnerability. An attacker can construct malicious requests to cause SSRF without logging in, attack intranet services, and leak sensitive information.
Details
- visit https://chat-preview.lobehub.com/
- click settings -> llm -> openai
- fill the OpenAI API Key you like
- fill the proxy address that you want to attack (e.g. a domain that resolved to a local ip addr like 127.0.0.1.xip.io) (the address will concat the path "/chat/completions" which can be bypassed with sharp like "http://172.23.0.1:8000/#")
- then lobe will echo the ssrf result
The jwt token header X-Lobe-Chat-Auth strored proxy address and OpenAI API Key, you can modify it to scan internal network in your target lobe-web.
