IBM Cloud Pak for Business Automation 18.0.0, 18.0.1, 18.0.2, 19.0.1, 19.0.2, 19.0.3, 20.0.1, 20.0.2, 20.0.3, 21.0.1, 21.0.2, 21.0.3, 22.0.1, and 22.0.2 allows restricting access to organizational data to valid contexts. The fact that tasks of type comment can be reassigned via API implicitly grants access to user queries in an unexpected context.
