CVE-2024-9216 | Authentication Bypass in gaizhenbiao/ChuanhuChatGPT

Exp

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. This allows an attacker to pass another user's username to the get_model function, thereby gaining unauthorized access to that user's chat history.

Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)

Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
