AI-suggested

Upgrade Apache Airflow to version 3.4.0 or later, where connection credentials are treated as write-only, effectively mitigating this vulnerability. No additional action is required if already using 3.4.0 or newer.

Description

The Apache Airflow connections API did not mask the apprise provider's `config` connection extra, which can embed notification-service credentials. A user with permission to read connections could retrieve it in cleartext, although Airflow 3 treats connection credentials as write-only. Users are advised to upgrade to apache-airflow 3.4.0 or later.
