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.
