## What is CVE-2024-9216?

CVE-2024-9216 is a high-severity authentication bypass vulnerability in gaizhenbiao/chuanhuchatgpt, published on 20 Mar 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

An authentication bypass vulnerability exists in gaizhenbiao/ChuanhuChatGPT, as of commit 3856d4f, allowing any user to read and delete other users' chat history. The vulnerability arises because the username is provided via an HTTP request from the client side, rather than being read from a secure source like a cookie.
