The vulnerability allows a remote user to suppress asset-triggered scheduling.

The vulnerability exists due to improper authorization in the asset queued-events DELETE endpoints when handling DELETE requests. A remote user can delete queued asset events for Dags they can read to suppress asset-triggered scheduling.
