CVE-2026-57590 · Severity: high · CVSS 8.1 · Published 2026-09-24

Apache DolphinScheduler is a workflow orchestration platform used to manage and schedule tasks across enterprise environments. A missing authorization check in the Task Group APIs allows authenticated users to access task groups they should not have permission to reach, potentially exposing sensitive workflow configurations and data. An attacker could view, modify, or delete task groups belonging to other projects without proper authorization.

## Technical details

The Task Group APIs in Apache DolphinScheduler fail to verify whether an authenticated user has permission to access the associated project before granting access to the task group. This is an authorization bypass vulnerability (broken access control) requiring authentication but no elevated privileges. An attacker with valid credentials can request task groups from projects they do not have access to, bypassing project-level authorization controls. The issue is fixed in version 3.4.3.
