CVE-2020-13927

9.8 criticalKEVEPSS 100%

Critical (9.8) in Apache Airflow's Experimental API. In CISA KEV since 2022-01-18. EPSS 100% chance of exploitation in the next 30 days. Fixed in apache-airflow 1.10.11.

The previous default setting for Airflow's Experimental API was to allow all API requests without authentication, but this poses security risks to users who miss this fact. From Airflow 1.10.11 the default has been changed to deny all requests by default and is documented at https://airflow.apache.org/docs/1.10.11/security.html#api-authentication. Note this change fixes it for new installs but existing users need to change their config to default `[api]auth_backend = airflow.api.auth.backend.deny_all` as mentioned in the Updating Guide: https://github.com/apache/airflow/blob/1.10.11/UPDATING.md#experimental-api-will-deny-all-request-by-default
