Description

The `example_dag_decorator` example Dag shipped with Apache Airflow validated an IP address fetched over HTTP with Python's `ipaddress` module and then placed it into a shell command. `ipaddress` accepts IPv6 zone identifiers containing arbitrary characters, so when example Dags are loaded (`load_examples` enabled), a user who can trigger that Dag with a custom `url` parameter could point it at a server whose response injects shell commands run on the worker. This is an incomplete fix for CVE-2025-54941; users who upgraded for CVE-2025-54941 should upgrade again. Users are advised to upgrade to apache-airflow 3.4.0 or later, or to disable example Dags (`load_examples = False`), which is recommended for production.
