CVE-2026-71183

Status: DeferredHigh (7.1)—

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.
