Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Airflow versions 3.3.0 up to but not including 3.3.1 are vulnerable. A Dag author, who can control a task instance's stored keyword arguments through the task execution API, can trigger arbitrary module import and object instantiation inside the scheduler process or stop the scheduler job; no non-default configuration is needed. Upgrade to apache-airflow 3.3.1 or later. Deployments that applied the fix for CVE-2026-58076 must also upgrade.
