{"id":"BIT-airflow-2026-68970","summary":"Apache Airflow: 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.","aliases":["CVE-2026-68970","PYSEC-2026-3712"],"modified":"2026-09-08T08:45:30.338723182Z","published":"2026-08-17T05:39:31.799Z","database_specific":{"cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"FIX","url":"https://github.com/apache/airflow/pull/70891"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/kkrlnbsk47oght4h38mcd3h2kcb8dt28"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68970"},{"type":"ADVISORY","url":"https://www.cve.org/CVERecord?id=CVE-2026-59244"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.3.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2026-68970.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
