{"schema_version": "1.6.1", "id": "CVE-2026-68970", "summary": "Values of a list-shaped Variable are not masked in task logs and the Rendered Templates UI", "details": "Apache Airflow's Task SDK did not mask the contents of a Variable whose JSON value is a list, so secrets stored in that shape appeared in cleartext in task logs and in the Rendered Templates UI. Masking was applied only when the deserialized value was a string or a dict; a list at the top level matched neither and was returned unmasked. Any authenticated user able to read the logs or rendered templates of a task that references such a Variable could recover the values, with no special configuration required. This is the list-shaped counterpart of CVE-2026-59244, whose fix covered the dict case only, so deployments that upgraded in response to that advisory remain affected and must upgrade again. Users are advised to upgrade to apache-airflow 3.3.1 or later.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "0"}, {"fixed": "3.3.1"}]}]}], "references": [{"type": "WEB", "url": "https://github.com/apache/airflow/pull/70891"}, {"type": "WEB", "url": "https://www.cve.org/CVERecord?id=CVE-2026-59244"}, {"type": "WEB", "url": "https://lists.apache.org/thread/kkrlnbsk47oght4h38mcd3h2kcb8dt28"}]}
