CVE-2026-81569 Details
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.
A vulnerability allowing improper authorization has been identified in Apache DolphinScheduler versions prior to 3.4.3. This issue arises in the management of sub-workflow tasks, where an authenticated user lacking permission to access a specific project can still reference and invoke workflows from that project. The system fails to adequately verify whether the user has the necessary permissions to execute the referenced workflow or access its associated project. Consequently, this oversight enables users to bypass project-level authorization controls, leading to the execution of workflows in unauthorized projects. Exploiting this vulnerability could result in the unauthorized execution of workflow tasks and access to the resources or data associated with the targeted workflow.
Users are advised to upgrade to Apache DolphinScheduler version 3.4.3 or later, which addresses this vulnerability.
