description

Apache DolphinScheduler API versions before 3.4.3 do not properly enforce project authorization for certain task-instance operations. An authenticated user may stop task instances or create savepoints in projects they are not permitted to access.

mitigation

Upgrade org.apache.dolphinscheduler:dolphinscheduler-api to version 3.4.3 or later.

fixed in 3.4.3
