Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Airflow versions before 3.3.2 are affected: the /assets/events API returned asset events for all Dags with no filter by the caller's Dag-level read permissions. An authenticated user with asset-read access can see event details, including source Dag ID, task ID, run ID and timestamps, for Dags they should not be able to read, and the total count and pagination reveal that hidden Dags exist. Upgrade to apache-airflow 3.3.2 or later; no workaround is listed.
