CVE-2026-59244

Name of the Vulnerable Software and Affected Versions Apache Airflow versions prior to 3.3.1

Description The secrets masker fails to mask var.json Variable values when the value is a dictionary within the Rendered Templates UI. This occurs because the dictionary value fails an isinstance(str) guard, causing secrets stored as JSON Variables and referenced in templates via var.json to be displayed in cleartext to any user with access to the Rendered Templates view of the task.

Recommendations Upgrade to apache-airflow version 3.3.1 or later.
