Authorization Bypass in Apache DolphinScheduler

Publication date: 2026-10-08

Last updated on: 2026-10-08

Assigner: Apache Software Foundation

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.

Executive Summary

This is an authorization vulnerability in Apache DolphinScheduler where authenticated users can access sensitive data source information they are not permitted to view. The /unauth-datasource and /authed-datasource endpoints fail to enforce proper access controls, allowing users to retrieve connection details including passwords for data sources they should not access.

Detection Guidance

Check if Apache DolphinScheduler endpoints /unauth-datasource or /authed-datasource are accessible without proper authorization. Use curl commands to test these endpoints for sensitive data exposure. Example: curl -u username:password http://target-server/unauth-datasource

Impact Analysis

If exploited, this vulnerability could allow unauthorized users to obtain database credentials and access sensitive data. Attackers could use the disclosed passwords to connect to databases directly, potentially leading to data breaches, unauthorized data manipulation, or further network compromise depending on the data source's role.

Compliance Impact

This vulnerability likely violates compliance requirements for data protection standards like GDPR and HIPAA, which mandate strict access controls and protection of sensitive data. Exposure of database credentials and unauthorized data access could result in regulatory penalties, legal liabilities, and reputational damage due to non-compliance with data security obligations.

Mitigation Strategies

Immediately upgrade Apache DolphinScheduler to version 3.4.3 or later to fix the authorization vulnerability in the /unauth-datasource and /authed-datasource endpoints.
