Vulnerability ID VCID-ezmu-8g1y-e3hz
Aliases CVE-2025-68438
GHSA-3qmm-r55x-hpxx
PYSEC-2026-9
Summary 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
