CVE-2026-101031

Apache Airflow: Shell command injection in the example_dag_decorator example Dag via an IPv6 zone identifier

No exploitation reported by the sources we read.

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

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.
