This is an incomplete fix for CVE-2025-54941; users who upgraded for CVE-2025-54941 should upgrade again. Users are advised to upgrade to apache-airflow 3.4.0 or later, or to disable example Dags (`load_examples = False`), which is recommended for production.","score":9.1,"severity":"critical","published":"2026-11-09T09:44:39.236Z","modified":"2026-11-12T16:11:23.932Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Apache Software Foundation","name":"Apache Airflow","platforms":[],"versions":[{"version":"3.0.5","status":"affected","lessThan":"3.4.0","versionType":"semver"}],"defaultStatus":"unaffected","packageURL":"pkg:pypi/apache-airflow-core","packageIdentity":{"ecosystem":"PyPI","name":"apache-airflow-core"},"cpes":[],"source":"apache","url":"https://www.cve.org/CVERecord?id=CVE-2026-101031"}],"remediation":[],"references":["https://github.com/apache/airflow/pull/73787","https://www.cve.org/CVERecord?id=CVE-2025-54941","https://lists.apache.org/thread.html/p53zxybld58wv722c7zxk0w8d2rnkfwk"],"sources":[{"name":"CVE","id":"CVE-2026-101031","modified":"2026-11-12T16:11:23.932Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-101031"}],"assessments":[{"source":"CISA-ADP","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1}],"sourceAffected":[],"observedAt":"2026-11-12T23:57:58.513Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T00:15:33.603Z"},"coverage":[{"source":"NVD","status":"no-result","checkedAt":"2026-11-09T09:55:34.688Z","attemptedAt":"2026-11-09T09:55:34.688Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-11-09T09:55:34.759Z","attemptedAt":"2026-11-09T09:55:34.759Z"},{"source":"EUVD","status":"no-result","checkedAt":"2026-11-09T09:55:34.626Z","attemptedAt":"2026-11-09T09:55:34.626Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-11-09T09:55:34.764Z","attemptedAt":"2026-11-09T09:55:34.764Z"}],"evidence":[],"aiSummary":{"text":"Apache Airflow versions before 3.4.0 are vulnerable to shell command injection via an IPv6 zone identifier in the example_dag_decorator example Dag.
