CVE-2025-54831
Description
Apache Airflow 3 introduced a change to the handling of sensitive information in Connections. The intent was to restrict access to sensitive connection fields to Connection Editing Users, effectively applying a "write-only" model for sensitive values.
In Airflow 3.0.3, this model was unintentionally violated: sensitive connection information could be viewed by users with READ permissions through both the API and the UI. This behavior also bypassed the AIRFLOW__CORE__HIDE_SENSITIVE_VAR_CONN_FIELDS configuration option.
This issue does not affect Airflow 2.x, where exposing sensitive information to connection editors was the intended and documented behavior.
Users of Airflow 3.0.3 are advised to upgrade Airflow to >=3.0.4.
