## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> Apache Airflow versions before 3.3.2 let any authenticated user who can read a Dag delete that Dag's queued asset events, which suppresses asset-triggered scheduling for it. The affected endpoints check read permission instead of edit permission. Upgrade to Apache Airflow 3.3.2 or later.
