CVAT is an open source interactive video and image annotation tool for computer vision. From 2.68.0 until 2.70.0, the audio-task annotation guide renderer in cvat-ui/src/audio/components/annotation-page/audio-workspace/top-bar/audio-right-group.tsx passes attacker-controlled guide Markdown to MDEditor without the rehype-sanitize plugin. A user who can create or edit an annotation guide can store malicious JavaScript that executes when another user opens the guide. The script can issue arbitrary CVAT requests with the victim user's privileges. This issue is fixed in version 2.70.0.
