Description

Apache Airflow: Secrets in rendered templates could contain parts of sensitive values when truncated

In Apache Airflow versions before 3.1.6, when rendered template fields in a Dag exceed [core] max_templated_field_length, sensitive values could be exposed in cleartext in the Rendered Templates UI. This occurred because serialization of those fields used a secrets masker instance that did not include user-registered mask_secret() patterns, so secrets were not reliably masked before truncation and display.

Users are recommended to upgrade to 3.1.6 or later, which fixes this issue
