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.

A bug in Apache Airflow's rendered-template field handling caused nested sensitive-key masking (e.g. nested password / token / secret / api_key keys inside a JSON template structure) to be bypassed when the rendered field exceeded [core] max_templated_field_length: Airflow stringified the structure before redaction, losing the nested key context, and persisted the plaintext value into rendered_fields. An authenticated UI/API user with permission to read rendered template fields could harvest secret values intended to be masked. Affects deployments where Dag authors pass structured JSON to operators with nested sensitive keys. This is a variant of CWE-200 previously addressed for the user-registered mask_secret() patterns in CVE-2025-68438; that fix did not cover the nested sensitive-keyword allowlist. Users who already upgraded for CVE-2025-68438 should additionally upgrade to apache-airflow 3.2.2 or later to cover the nested-key path.
