CVE-2026-23526: Cvat Computer Vision Annotation Tool

High severity, CVSS 8.8. EPSS: 0.3% chance of exploitation in the next 30 days.

CVAT is an open source interactive video and image annotation tool for computer vision. In versions 1.0.0 through 2.54.0, users that have the staff status may freely change their permissions, including giving themselves superuser status and joining the admin group, which gives them full access to the data in the CVAT instance. Version 2.55.0 fixes the issue. As a workaround, review the list of users with staff status and revoke it from any users that are not expected to have superuser privileges.

Affected products

• Cvat Computer Vision Annotation Tool: from 1.0.0, before 2.55.0 (fixed in 2.55.0)
