CVE-2026-66083

MediumCVSS 6.5/10Last modified Oct 6, 2026

Description

The /datasources/unauth-datasource endpoint does not properly enforce data source authorization. An authenticated user can invoke this endpoint to obtain information about data sources they are not authorized to access. This may expose data source configuration and other sensitive metadata, depending on the fields returned by the endpoint.

This issue affects Apache DolphinScheduler: before 3.4.3.

Users are recommended to upgrade to version 3.4.3, which fixes the issue.
