CVE-2026-71183Network attack vectorHinoki check available

Authenticated password disclosure via missing data-source authorization

Published Oct 8, 2026 · Updated Oct 8, 2026

Authorization bypass in Apache DolphinScheduler before 3.4.3 allows remote authenticated users to read passwords via data-source APIs. The /unauth-datasource and /authed-datasource endpoints return connection details and passwords without enforcing data-source access controls. A logged-in account lacking permission for the returned data sources is sufficient; subsequent database access depends on database reachability and the disclosed credentials' privileges.
