A remote code/command injection vulnerability was discovered in one of the example DAGs shipped with Airflow which would allow any authenticated user to run arbitrary commands as the user running airflow worker/scheduler (depending on the executor in use). If you already have examples disabled by setting load_examples=False in the config then you are not vulnerable.","published":"2020-07-17T00:15:10.337Z","modified":"2026-10-20T10:51:46.037023320Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.99189,"percentile":0.99933,"asOf":"2026-09-16"},"cisaKev":null,"exploitsKnown":10,"affectedPackages":[{"ecosystem":"PyPI","name":"apache-airflow","fixedVersion":"1.10.11rc1"}],"fix":{"url":"https://github.com/apache/airflow/pull/9143","label":"apache/airflow#9143"},"references":[{"type":"ADVISORY","url":"https://lists.apache.org/thread.html/r7255cf0be3566f23a768e2a04b40fb09e52fcd1872695428ba9afe91%40%3Cusers.airflow.apache.org%3E"},{"type":"ADVISORY","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2020-11978"},{"type":"EVIDENCE","url":"http://packetstormsecurity.com/files/162908/Apache-Airflow-1.10.10-Remote-Code-Execution.html"},{"type":"EVIDENCE","url":"http://packetstormsecurity.com/files/174764/Apache-Airflow-1.10.10-Remote-Code-Execution.html"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-11978"},{"type":"WEB","url":"https://github.com/apache/airflow/pull/9143"},{"type":"WEB","url":"https://github.com/apache/airflow/commit/2fa51576e1283f5732e38fada686fd248d9c3a1e"},{"type":"WEB","url":"https://github.com/apache/airflow/commit/4d8599e8b0520ff4226fbad72f724afae50fdd08"},{"type":"PACKAGE","url":"https://github.com/apache/airflow"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/apache-airflow/PYSEC-2020-14.yaml"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-20T10:51:46.037023320Z"}}
