Deeper analysis
CVE-2024-8613 is a vulnerability in gaizhenbiao/chuanhuchatgpt version 20240802 that enables attackers to access, copy, and delete other users' chat histories. The issue stems from improper handling of session data combined with a lack of access control mechanisms, allowing unauthorized viewing and manipulation of chat histories belonging to other users. It has been assigned a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-639.
The vulnerability can be exploited by attackers who have low privileges, such as authenticated users on the system, over a network connection with low attack complexity and no requirement for user interaction. Successful exploitation grants high-impact access to sensitive chat history data, enabling the attacker to read confidential conversations (high confidentiality impact), modify or copy them (high integrity impact), and delete them (high availability impact).
Advisories point to a fix via a commit in the project's GitHub repository at https://github.com/gaizhenbiao/chuanhuchatgpt/commit/526c615c437377ee9c71f866fd0f19011910f705, with additional details and a bounty report available on Huntr at https://huntr.com/bounties/76258774-b011-4044-9c3d-c2609b1cbd29. Security practitioners should update to a patched version to mitigate the risks.
