CVE-2024-7767Public exploitNetwork attack vector

Authenticated chat disclosure and modification via missing authorization

Published Mar 20, 2025 · Updated Oct 15, 2025

Missing authorization in Onyx 0.3.94 allows remote authenticated users to view, modify, and delete an administrator's chats. The public record does not identify the affected endpoint or code path, but states that the first-created account can operate on chats owned by an administrator. A valid account in the first-created-user position is required, exposing chat contents and permitting integrity loss without service interruption.
