What is CVE-2026-33030?

Nginx UI, the web user interface for Nginx, is affected by an Insecure Direct Object Reference vulnerability. Authenticated users can exploit this flaw to gain unauthorized access, modification, or deletion of resources owned by other users. Due to the lack of a user_id field in the application's main Model struct, it fails to verify ownership for resource queries, leading to a security lapse in multi-user settings. As of now, there are no publicly available patches to rectify this issue, which could potentially allow further exploitation.
