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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N","score":2.7},"cwes":["CWE-295"],"references":["http://www.openwall.com/lists/oss-security/2024/04/19/3","https://docs.python.org/3/library/ssl.html#best-defaults","https://github.com/apache/airflow/blob/95e26118b828c364755f3a8c96870f3591b01c31/airflow/providers/ftp/hooks/ftp.py#L280","https://github.com/apache/airflow/pull/38266","https://lists.apache.org/thread/265t5zbmtjs6h9fkw52wtp03nsbplky2"],"products":["apache:apache-airflow-providers-ftp"],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2024-29733","score":0.00631,"percentile":0.50267,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3gg8-mc87-cq3h","url":"https://osv.dev/vulnerability/GHSA-3gg8-mc87-cq3h","summary":"Improper Certificate Validation vulnerability in Apache Airflow FTP Provider","modified":"2026-07-07T17:56:42.222293862Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow-providers-ftp","purl":"pkg:pypi/apache-airflow-providers-ftp","ranges":["<3.7.0"],"fixed":["3.7.0"]}]},{"id":"PYSEC-2026-1148","url":"https://osv.dev/vulnerability/PYSEC-2026-1148","summary":"Improper Certificate Validation vulnerability in Apache Airflow FTP Provider","modified":"2026-07-07T17:46:27.151333223Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow-providers-ftp","purl":"pkg:pypi/apache-airflow-providers-ftp","ranges":["<3.7.0"],"fixed":["3.7.0"]}]}],"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).
