CVE-2026-71183 Details
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.
An authorization vulnerability exists in Apache DolphinScheduler versions prior to 3.4.3. This vulnerability allows authenticated users to access information about data sources they are not authorized to use, through the /unauth-datasource and /authed-datasource endpoints. These endpoints do not properly enforce data source access controls, resulting in the unintentional disclosure of sensitive connection details, including passwords. Exploiting this vulnerability could lead to unauthorized access to the databases associated with the exposed credentials.
Users are advised to upgrade to Apache DolphinScheduler version 3.4.3 or later, which addresses this vulnerability.
