CVE-2026-23516: Cvat Computer Vision Annotation Tool

Medium severity, CVSS 5.4. EPSS: 0.2% chance of exploitation in the next 30 days.

CVAT is an open source interactive video and image annotation tool for computer vision. In versions 2.2.0 through 2.54.0, an attacker is able to execute arbitrary JavaScript in a victim user's CVAT UI session, provided that they are able to create a maliciously crafted label in a CVAT task or project, then get the victim user to either edit that label, or view a shape that refers to that label; and/or get the victim user to upload a maliciously crafted SVG image when configuring a skeleton. This gives the attacker temporary access to all CVAT resources that the victim user can access. Version 2.55.0 fixes the issue.

Affected products

• Cvat Computer Vision Annotation Tool: from 2.2.0, before 2.55.0 (fixed in 2.55.0)
