Description

A server-side request forgery (SSRF) vulnerability in duhow/xiaoai-patch through commit fb07049 allows a remote attacker to make the Xiaomi smart speaker perform HTTP requests to arbitrary internal or external URLs. The /auth endpoint in api/main.py uses the user-supplied url POST parameter to redirect to a Home Assistant instance without validating the destination URL, enabling internal network scanning and access to internal services.
