Apache Airflow Command Injection

[ Why it matters ]Priority signals

• Exploited in the wild: on CISA's Known Exploited Vulnerabilities list since 2022-01-18
• EPSS: 99% chance of exploitation in the next 30 days (higher than 100% of CVEs)

[ Description ]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.

CISA: A remote code/command injection vulnerability was discovered in one of the example DAGs shipped with Airflow.
