CVE-2025-54831Network attack vectorHinoki check available

Credential disclosure via unmasked Connection responses

Published Sep 26, 2025 · Updated Sep 26, 2025

Information disclosure in Apache Airflow 3.0.3 allows remote authenticated users with READ permission to view sensitive Connection data. The Connections API and UI return unmasked credentials instead of enforcing the Airflow 3 write-only policy, even when AIRFLOW__CORE__HIDE_SENSITIVE_VAR_CONN_FIELDS is enabled. Read access to Connections is sufficient; exposed values can reveal stored credentials, with no reported integrity or availability impact.
