CVE-2026-101031

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.
