The record

xianyu-auto-reply-fix through 2.0.7 contains a missing authorization vulnerability in the POST /send-message endpoint that allows unauthenticated attackers to send messages from other users' accounts using publicly known default API secrets. Attackers can supply the hard-coded api_key and another user's cookie_id, plus chosen chat_id, to_user_id and message values, to send arbitrary Xianyu messages to buyers from that merchant account.
