Description

AI Translation Available

A missing authorization vulnerability exists in the `query-dynamic-sub-workflows` API of Apache DolphinScheduler. The API does not properly verify whether the authenticated user has permission to access the workflows being queried.

An authenticated user who does not have permission to access a specific project can invoke the API with parameters referencing workflows belonging to that project and retrieve workflow information. This allows users to access workflow data outside their authorized project scope, resulting in unauthorized information disclosure.

This issue affects Apache DolphinScheduler: from 3.2.0 before 3.4.3.

Users are recommended to upgrade to version 3.4.3, which fixes the issue.
