Implementing proper certificate validation by passing context=ssl.create_default_context() during FTP_TLS instantiation is used as mitigation to validate the certificates properly.\n\nThis issue affects Apache Airflow FTP Provider: before 3.7.0.\n\nUsers are recommended to upgrade to version 3.7.0, which fixes the issue.","published":"2024-04-21T17:21:55.722Z","modified":"2026-08-08T03:48:02.978364986Z","cvss":{"score":2.7,"severity":"LOW","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"apache-airflow-providers-ftp","fixedVersion":"3.7.0"}],"fix":{"url":"https://github.com/apache/airflow/pull/38266","label":"apache/airflow#38266"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/04/19/3"},{"type":"WEB","url":"https://pypi.python.org"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/29xxx/CVE-2024-29733.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/265t5zbmtjs6h9fkw52wtp03nsbplky2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-29733"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/38266"},{"type":"ARTICLE","url":"https://docs.python.org/3/library/ssl.html#best-defaults"},{"type":"ARTICLE","url":"https://github.com/apache/airflow/blob/95e26118b828c364755f3a8c96870f3591b01c31/airflow/providers/ftp/hooks/ftp.py#L280"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:48:02.978364986Z"}}
