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.

• CWE-863Incorrect AuthorizationThe product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
