# CVE-2026-107474: Apache Airflow: Connections API: apprise connection "config" extra returned in cleartext

Status: published. Published: 2026-11-09. Updated: 2026-11-09.

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.
