What is CVE-2025-49135?

CVAT, an open-source tool for interactive video and image annotation, suffers from a lack of validation in its project and task backup import process. This vulnerability allows users with a basic account to potentially access and utilize files uploaded by other users if they know the filenames. This could lead to unauthorized access to sensitive data, as the application fails to confirm proper ownership of the files during project creation. For protection against this issue, users are encouraged to upgrade to CVAT version 2.40.0 or more recent versions, as no alternative workarounds are available.

Affected Version(s)

cvat >= 2.2.0, < 2.40.0
