What is CVE-2026-23526?

CVAT, an open-source interactive video and image annotation tool used for computer vision projects, has a vulnerability that allows users with staff status to manipulate their permissions. Specifically, such users can grant themselves superuser access and become members of the admin group, which results in full control over the CVAT instance and its data. The issue has been resolved in version 2.55.0 of the software. As a preventive measure, it is advisable to review all staff status users and revoke unnecessary superuser privileges to mitigate risks.
