BIT-AIRFLOW-2026-67587 Apache Airflow: DAG-author remote code execution on the Scheduler via a Serde `Callback` deserialization gadget

Apache Airflow's Task SDK rebuilt a Callback object from serialized data by re-running its constructor, which imports the module named by the stored callback path. Because SyncCallback is itself an Airflow class it passes the default alloweddeserializationclasses allow-list, so tightening that...
