AI-suggested

Users should upgrade Apache Airflow to version 3.4.0 or later to remediate this vulnerability. The issue affects only deployments that have enabled the non-default [core] test_connection setting, so disabling this setting can also mitigate the risk if upgrading is not immediately possible.

Description

Apache Airflow versions with the non-default [core] test_connection setting enabled have a vulnerability where asynchronous connection tests improperly handle permissions. Specifically, users with create permission but without edit permission can overwrite existing connections if the test completes and commits the connection under an existing ID. This issue is fixed in Apache Airflow 3.4.0 and later.
