Summary
Apache Airflow exposes sensitive JSON Variable values through the Bulk Variables API
Details

The Bulk Variables API in Apache Airflow called the redactor without passing the variable's key, so the key-based should_hide_value_for_key check (which triggers on secret-suffixed key names like *_password / *_token / *_secret) could not fire for JSON-decodable variable values. An authenticated UI/API user with bulk Variable read permission could retrieve plaintext values from JSON variables whose key would otherwise trigger redaction. Affects deployments that store sensitive values in JSON-typed Airflow Variables under secret-suffixed key names. Users are advised to upgrade to apache-airflow 3.3.0 or later (the fix landed on main after 3.2.2; no 3.2.x backport).
