CVE-2026-33030

Nginx UI is a web user interface for the Nginx web server. In versions 2.3.3 and prior, Nginx-UI contains an Insecure Direct Object Reference (IDOR) vulnerability that allows any authenticated user to access, modify, and delete resources belonging to other users. The application's base Model struct lacks a user_id field, and all resource endpoints perform queries by ID without verifying user ownership, enabling complete authorization bypass in multi-user environments. At time of publication, there are no publicly available patches.
