How to Fix CVE-2026-71899

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-71899, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A missing authorization vulnerability exists in the `query-dynamic-sub-workflows` API of Apache DolphinScheduler. The API does not properly verify whether the authenticated user has permission to access the workflows being queried. An authenticated user who does not have permission to access a specific project can invoke the API with parameters referencing workflows belonging to that project and retrieve workflow information. This allows users to access workflow data outside their authorized project scope, resulting in unauthorized information disclosure. This issue affects Apache DolphinScheduler: from 3.2.0 before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue.
