CVE-2026-81569: Vulnerability in Apache Software Foundation Apache DolphinScheduler
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.
AI Analysis
Technical Summary
CVE-2026-81569 is an improper authorization vulnerability in Apache DolphinScheduler affecting versions prior to 3.4.3. The vulnerability occurs because the system does not properly verify whether an authenticated user has permission to execute a referenced workflow or access its project when handling sub-workflow tasks. This allows users to bypass project-level authorization controls and execute workflows in unauthorized projects.
Potential Impact
Successful exploitation enables an authenticated user without proper project permissions to execute workflows in unauthorized projects, potentially accessing resources or data associated with those workflows. This could lead to unauthorized actions within the system and exposure of sensitive information tied to the targeted workflows.
Mitigation Recommendations
Users should upgrade Apache DolphinScheduler to version 3.4.3 or later, where this improper authorization vulnerability has been fixed. No other mitigation steps are indicated.
