In short
Apache Airflow's example workflows contained a security flaw that allowed authenticated users to execute arbitrary commands on the server with the privileges of the Airflow process. This could give attackers full control over the system running Airflow.
Technical detail
CWE-78 command injection vulnerability in Airflow's example DAGs allows authenticated attackers to achieve remote code execution via unsafe parameter handling in one of the shipped example workflows. Pre-condition requires load_examples=True (default). Impact includes code execution with airflow worker/scheduler privileges depending on executor configuration.
Summary generated and translated by AI from the official description.
An issue was found in Apache Airflow versions 1.10.10 and below. A remote code/command injection vulnerability was discovered in one of the example DAGs shipped with Airflow which would allow any authenticated user to run arbitrary commands as the user running airflow worker/scheduler (depending on the executor in use). If you already have examples disabled by setting load_examples=False in the config then you are not vulnerable.
