Apache Airflow <3.1.6 Log Leak via Proxy Credentials in Connection Fields
CVE-2025-68675 Published on January 16, 2026
Apache Airflow: proxy credentials for various providers might leak in task logs
In Apache Airflow versions before 3.1.6, and 2.11.1 the proxies and proxy fields within a Connection may include proxy URLs containing embedded authentication information. These fields were not treated as sensitive by default and therefore were not automatically masked in log output. As a result, when such connections are rendered or printed to logs, proxy credentials embedded in these fields could be exposed.
Users are recommended to upgrade to 3.1.6 or later for Airflow 3, and 2.11.1 or later for Airflow 2 which fixes this issue
