Title
Apache Airflow: Reserved serialization keys in Dag run conf crash the scheduler or are rebuilt as objects in the Triggerer via deadline callbacks
Summary
Apache Airflow did not reject reserved serialization keys inside a Dag run's `conf`. A user allowed to trigger a Dag that uses a deadline alert with an asynchronous callback could pass a `conf` that, once the deadline was missed, either crashed the scheduler repeatedly or was rebuilt into objects inside the Triggerer. Users are advised to upgrade to apache-airflow 3.4.0 or later.
Severity
