Overview

CVE-2026-81569 is a medium-severity vulnerability. It was published on September 29, 2026 and has a CVSS 3.1 base score of 4.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.3, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

An improper authorization vulnerability exists in the handling of sub-workflow tasks. An authenticated user who does not have permission to access a target project can reference and invoke a workflow belonging to that project through a sub-workflow task.

The system does not properly verify whether the user has permission to execute the referenced workflow or access its project. As a result, the user can bypass project-level authorization controls and cause workflows in unauthorized projects to be executed.

Successful exploitation may allow unauthorized execution of workflow tasks and access to the resources or data available to the target workflow.

This issue affects Apache DolphinScheduler: before 3.4.3.

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

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
