CVE-2026-48828
Published:July 07, 2026
Updated:August 04, 2026
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).
