CVE-2024-4520
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn improper access control vulnerability exists in the gaizhenbiao/chuanhuchatgpt application, specifically in version 20240410. This vulnerability allows any user on the server to access the chat history of any other user without requiring any form of interaction between the users. Exploitation of this vulnerability could lead to data breaches, including the exposure of sensitive personal details, financial data, or confidential conversations. Additionally, it could facilitate identity theft and manipulation or fraud through the unauthorized access to users' chat histories. This issue is due to insufficient access control mechanisms in the application's handling of chat history data.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisThe application checks who you are but not whether you're allowed to perform a given action, so any authenticated user can reach things meant for others. This is the classic “change the ID in the URL” bug. The fix is an authorization check on every request, evaluated against the acting user's permissions.
