Severity: moderate
Affected versions:
- Apache DolphinScheduler before 3.4.3
Description:
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.
