Deserialization reconstructs nested objects of classes permitted by the deserialization allow-list \u2014 which by default includes Airflow\u0027s own classes \u2014 and runs their constructors inside the scheduler process before the check can reject the value. A Dag author, who controls a task\u0027s `next_kwargs` through the task execution API, can therefore still trigger constructor execution in the scheduler when the `awaiting_input` timeout sweep processes the task, and in the API server when the task instance is served to a worker using an older Execution API version; no non-default configuration is required. Versions before 3.3.0 are not affected. This is an incomplete fix for CVE-2026-67260: deployments that upgraded to 3.3.1 for that issue must also upgrade to apache-airflow 3.4.0 or later."
