## Affected

- cvat-ai cvat: from 2.17.0, fixed in 2.72.0

## Description

CVAT is an open source interactive video and image annotation tool for computer vision. From 2.17.0 until 2.72.0, a user with write access to a CVAT job can submit a batch automatic annotation request to RequestViewSet.create with inconsistent task and job IDs, and because the task ID determines the single active request slot, block automatic annotation for another task whose ID is known. This issue is fixed in version 2.72.0.

## What to do

- Check your stack: if you ship or depend on cvat-ai cvat, upgrade to a fixed version (2.72.0) per the references below.
