CVE-2026-71896Apache DolphinScheduler: Missing Authorization Checks Allow Unauthorized Disclosure of User Account Information
Medium 6.5
In plain English
A medium-severity incorrect authorization in Apache DolphinScheduler from Apache Software Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 18% of all known vulnerabilities).
Official 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.
