The Bulk Variables API in Apache Airflow called the redactor without passing the variable's key, so the key-based check (which triggers on secret-suffixed key names like / / ) 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 3.3.0 or later (the fix landed on after 3.2.2; no 3.2.x backport).

Are you affected?

Enter the version you run. The result uses only the ranges stored on this record.
