A missing authorization vulnerability exists in the query-dynamic-sub-workflows API of Apache DolphinScheduler. (CVE-2026-71899)
A missing authorization vulnerability exists in the `query-dynamic-sub-workflows` API of Apache DolphinScheduler. The API does not properly verify whether the authenticated user has permission to access the workflows being queried. An authenticated user who does not have permission to access a specific project can invoke the API with parameters referencing workflows belonging to that project and retrieve workflow information. This allows users to access workflow data outside their authorized project scope, resulting in unauthorized information disclosure. This issue affects Apache DolphinScheduler: from 3.2.0 before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue.
AI Analysis
Technical Summary
The query-dynamic-sub-workflows API in Apache DolphinScheduler does not properly verify whether an authenticated user has permission to access the workflows referenced in the API call. As a result, users can query workflows belonging to projects they are not authorized to access, leading to unauthorized information disclosure. This vulnerability affects Apache DolphinScheduler versions starting from 3.2.0 up to but excluding 3.4.3. The issue is fixed in version 3.4.3.
Potential Impact
Authenticated users without permission to specific projects can retrieve workflow information from those projects, resulting in unauthorized disclosure of potentially sensitive workflow data. There is no indication of remote code execution or privilege escalation beyond information disclosure.
Mitigation Recommendations
Users should upgrade Apache DolphinScheduler to version 3.4.3 or later, where this missing authorization vulnerability has been fixed. No other mitigation is indicated.
