CVE-2026-25219Network attack vector

Credential disclosure via incomplete secrets masking

Published Apr 15, 2026 · Updated Apr 15, 2026

Information disclosure in Apache Airflow before 3.1.8 allows remote authenticated users to read connection secrets through the UI or logs. The secrets masker omits access_key and connection_string from DEFAULT_SENSITIVE_FIELDS, leaving those values unredacted when connections are displayed or logged. Read permission is required, and exposed Azure Service Bus credentials can grant access to the connected service.
