AI analysis
Apache DolphinScheduler before 3.4.3 has an incorrect-authorization flaw (CWE-863) in the /unauth-datasource and /authed-datasource endpoints. An authenticated user who is not permitted to use a data source can call those endpoints and receive sensitive connection information, including data source passwords. Those credentials can then be used to reach the underlying databases. The issue affects all DolphinScheduler releases before 3.4.3; 3.4.3 is the fixed version. It is not listed in CISA KEV, has no known public proof of concept, and exploitation in the wild is not known.
What to do: Upgrade Apache DolphinScheduler to 3.4.3 or later. Treat data-source connection details and passwords as exposed to any authenticated user, rotate those credentials, and review database access logs for unexpected use of the disclosed accounts. Until upgrade, restrict who can reach the scheduler UI and API.

Description
An authorization vulnerability in Apache DolphinScheduler allows authenticated users to obtain information about data sources they are not authorized to access through the /unauth-datasource and /authed-datasource endpoints. These endpoints fail to enforce the required data source access controls and return sensitive connection information, including data source passwords. As a result, an authenticated user without permission to access a data source can retrieve its connection details and credentials. Successful exploitation exposes sensitive data source information and may enable unauthorized access to the underlying databases using the disclosed credentials. This issue affects Apache DolphinScheduler: before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue.
