AI-suggested

Users should upgrade Apache Airflow to version 3.4.0 or later, where this vulnerability is fixed. Alternatively, disabling example DAGs by setting load_examples = False is recommended for production environments to avoid exposure. Since this vulnerability is a regression of a previous fix, users who upgraded for CVE-2025-54941 should upgrade again to 3.4.0 or later.

Description

Apache Airflow versions from 3.0.5 up to but not including 3.4.0 contain an OS command injection vulnerability in the example_dag_decorator example DAG. This occurs because the DAG validates an IP address fetched over HTTP using Python's ipaddress module, which accepts IPv6 zone identifiers with arbitrary characters. These characters can be injected into shell commands executed on the worker, allowing command injection. This vulnerability is an incomplete fix of a previous issue (CVE-2025-54941). Users should upgrade to version 3.4.0 or later or disable example DAGs in production.
