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.
