{"id":"CVE-2026-48828","aliases":["BIT-airflow-2026-48828","GHSA-563f-2439-rmq4"],"url":"https://o3.security/vulnerability/CVE-2026-48828","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).","published":"2026-07-07T09:18:53.833Z","modified":"2026-09-04T19:40:35.759226107Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"apache-airflow","fixedVersion":"3.3.0"}],"fix":{"url":"https://github.com/apache/airflow/pull/67495","label":"apache/airflow#67495"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/07/07/2"},{"type":"WEB","url":"https://pypi.python.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48828.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/y9kf314t6dhnv994hr11wj3tbow847yc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48828"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/67495"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-04T19:40:35.759226107Z"}}
