Summary

Apache DolphinScheduler before 3.4.3 has an authorization bypass (CWE-863). Endpoints check permissions against the supplied project code but do not verify that the target schedule or workflow belongs to it. An authenticated user with permissions in one project can use another project's resource ID to change workflow availability there. Successful exploitation disrupts task execution in projects the user is not authorized to access.

Description from the CNA

An authorization bypass vulnerability in Apache DolphinScheduler allows authenticated users to perform unauthorized operations on workflow schedules, workflow definitions, and task instances in other projects. The affected endpoints check permissions against the supplied projectCode but fail to verify that the target resource belongs to that project. An authenticated user with the required permissions in one project can supply that project's code together with a resource identifier from another project, bypassing the target project's access restrictions. The affected endpoints include: * POST /projects/{projectCode}/schedules/{id}/online and /offline: Activate or deactivate workflow schedules in another project. * POST /projects/{projectCode}/workflow-definition/{code}/release: Change the ONLINE/OFFLINE state of workflow definitions in another project. Successful exploitation allows users to alter workflow availability and interfere with task execution in projects they are not authorized to access. This issue affects Apache DolphinScheduler: before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue.
