What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

An authorization vulnerability in Apache DolphinScheduler allows authenticated users to retrieve other users' account information through the /dolphinscheduler/users/list-all endpoint without the required permissions.

The endpoint fails to enforce the necessary authorization checks before returning user account information. As a result, an authenticated user can access account information they are not authorized to view.

Successful exploitation may expose sensitive user information and facilitate account enumeration.

This issue affects Apache DolphinScheduler: before 3.4.3.

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