Apache · Apache Airflow · CVE-2025-68438
**Name of the Vulnerable Software and Affected Versions**
Apache Airflow versions prior to 3.1.6
**Description**
When rendered template fields in a Dag exceed `max templated field length`, sensitive values could be exposed in cleartext in the Rendered Templates UI. This is due to the serialization of these fields using a secrets masker instance that did not include user-registered `mask secret()` patterns, resulting in unreliable masking of secrets before truncation and display.
**Recommendations**
Upgrade to version 3.1.6 or later to resolve this issue.
