CVE-2026-111455 · Runtime

Apache Airflow's asynchronous connection test checked permissions only when queued, so a user with create-only rights can overwrite a connection someone else created in the meantime. The overwrite happens when a test completes with commit_on_success.

Only Airflow deployments that turn on the non-default [core] test_connection setting are exposed. The risk is to teams where some users can create connections but not edit them, since those users can overwrite connections made by others.
Not affected if default-config, test-connection-disabled

[core] test_connection is enabled in airflow.cfg or the AIRFLOW__CORE__TEST_CONNECTION environment variable; only enabled deployments are affected.airflow version or pip show apache-airflow; versions before 3.4.0 are affected.3.4.0 or laterApache Airflow's asynchronous connection test checked permissions when the test was queued — only create permission when the connection ID did not exist yet — but, when the test completed with commit_on_success, wrote the tested connection under that ID. A user allowed to create but not edit connections could overwrite a connection someone else had created in the meantime. Only deployments that enable the non-default [core] test_connection setting are affected. Users are advised to upgrade to apache-airflow 3.4.0 or later.
