Name of the Vulnerable Software and Affected Versions Apache Airflow versions prior to 1.10.11

Description The issue is related to the Experimental API in Apache Airflow, which previously allowed all API requests without authentication by default. This poses security risks to users who are not aware of this setting. The vulnerability can be exploited by a remote attacker to bypass existing access restrictions and make API requests without authentication. From version 1.10.11, the default setting has been changed to deny all requests by default.

Recommendations For versions prior to 1.10.11, change the configuration to default [api]auth backend = airflow.api.auth.backend.deny all as mentioned in the Updating Guide to address the vulnerability.
