CVE-2020-11978
Apache Airflow Command Injection
Does this matter?
Known to be exploited in the wild (CISA KEV, CISA remediation deadline 18 July 2022). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.
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.
