NVD Description

Note: Versions mentioned in the description apply only to the upstream airflow-3 package and not the airflow-3 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Apache Airflow's secrets masker did not mask var.json Variable values whose value is a dict in the Rendered Templates UI — the dict value failed an isinstance(str) guard — so a secret stored as a JSON Variable and referenced in a template via var.json was displayed in cleartext to any user with access to that task's Rendered Templates view. Users are advised to upgrade to apache-airflow 3.3.1 or later, which masks nested Variable values regardless of type.
