{"cve":"CVE-2026-68970","nvd":{"published":"2026-08-12T16:17:19.853","modified":"2026-10-24T16:10:00.153","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-312"],"references":["https://github.com/apache/airflow/pull/70891","https://lists.apache.org/thread/kkrlnbsk47oght4h38mcd3h2kcb8dt28","https://www.cve.org/CVERecord?id=CVE-2026-59244"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-24T16:53:35.584907681+00:00"},"epss":{"cve":"CVE-2026-68970","score":0.0023,"percentile":0.13697,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-f3c2-j7g8-vpp8","url":"https://osv.dev/vulnerability/GHSA-f3c2-j7g8-vpp8","summary":"Apache Airflow Task SDK fails to mask list-shaped JSON Variables","modified":"2026-10-02T23:40:44.657103202Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.3.1"],"fixed":["3.3.1"]}]},{"id":"PYSEC-2026-3712","url":"https://osv.dev/vulnerability/PYSEC-2026-3712","summary":"","modified":"2026-10-15T14:45:07.487476001Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":["<3.3.1"],"fixed":["3.3.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
