CVAT: Missing path-containment validation in multiple entry points allows arbitrary path writes

CVAT is an open source interactive video and image annotation tool for computer vision. In versions 1.6.0 through 2.64.0, an attacker with write access to a cloud storage that's been added to a CVAT instance, or ability to add new cloud storages, is able to overwrite arbitrary files on the server's filesystem. This issue has been fixed in version 2.65.0.
