Apache Software Foundation
Parameter Value
CVSS 6.5 (MEDIUM)
Affected Versions before 3.4.3.
Fixed In 3.4.3
Type CWE-863 (Incorrect Authorization)
Vendor Apache Software Foundation
Public PoC No

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.
