CVE-2026-71183: CWE-863 Incorrect Authorization in Apache Software Foundation Apache DolphinScheduler
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.

Technical Analysis
CVE-2026-71183 is an authorization vulnerability in Apache DolphinScheduler affecting versions prior to 3.4.3. Authenticated users can retrieve sensitive connection details and passwords for data sources they are not authorized to access through the /unauth-datasource and /authed-datasource endpoints. The root cause is the failure of these endpoints to enforce required data source access controls, exposing sensitive credentials. Upgrading to Apache DolphinScheduler 3.4.3 addresses this vulnerability.
Potential Impact
Successful exploitation allows an authenticated user without proper permissions to obtain sensitive data source connection information, including passwords. This exposure may enable unauthorized access to the underlying databases, potentially compromising data confidentiality and integrity.
Mitigation Recommendations
Users should upgrade Apache DolphinScheduler to version 3.4.3 or later, where this authorization vulnerability has been fixed. No other mitigation steps are indicated by the vendor advisory.
