Summary
Apache Airflow: Bulk JSON Variables bypass should_hide_value_for_key - redact() called without the key
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).
