{"id":"PYSEC-2026-1148","summary":"Improper Certificate Validation vulnerability in Apache Airflow FTP Provider","details":"Improper Certificate Validation vulnerability in Apache Airflow FTP Provider.\n\nThe FTP hook lacks complete certificate validation in FTP_TLS connections, which can potentially be leveraged. 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.","aliases":["CVE-2024-29733","GHSA-3gg8-mc87-cq3h"],"modified":"2026-07-07T17:46:27.151333223Z","published":"2026-07-07T11:45:39.923405Z","references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-29733"},{"type":"WEB","url":"https://github.com/apache/airflow/pull/38266"},{"type":"WEB","url":"https://docs.python.org/3/library/ssl.html#best-defaults"},{"type":"PACKAGE","url":"https://github.com/apache/airflow"},{"type":"WEB","url":"https://github.com/apache/airflow/blob/95e26118b828c364755f3a8c96870f3591b01c31/airflow/providers/ftp/hooks/ftp.py#L280"},{"type":"WEB","url":"https://lists.apache.org/thread/265t5zbmtjs6h9fkw52wtp03nsbplky2"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/04/19/3"},{"type":"PACKAGE","url":"https://pypi.org/project/apache-airflow-providers-ftp"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-3gg8-mc87-cq3h"}],"affected":[{"package":{"name":"apache-airflow-providers-ftp","ecosystem":"PyPI","purl":"pkg:pypi/apache-airflow-providers-ftp"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.7.0"}]}],"versions":["1.0.0","1.0.0b1","1.0.0b2","1.0.0rc1","1.0.1","1.0.1rc1","1.1.0","1.1.0rc1","2.0.0","2.0.0rc1","2.0.0rc2","2.0.1","2.0.1rc1","2.1.0","2.1.0rc1","2.1.1","2.1.1rc1","2.1.2","2.1.2rc1","3.0.0","3.0.0rc1","3.0.0rc2","3.1.0","3.1.0rc1","3.2.0","3.2.0rc1","3.3.0","3.3.0rc1","3.3.0rc2","3.3.1","3.3.1rc1","3.4.0","3.4.0rc1","3.4.0rc2","3.4.1","3.4.1rc1","3.4.2","3.4.2rc1","3.5.0","3.5.0rc1","3.5.1","3.5.1rc1","3.5.2","3.5.2rc1","3.6.0","3.6.0rc1","3.6.1","3.6.1rc1","3.7.0rc1"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/apache-airflow-providers-ftp/PYSEC-2026-1148.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N"}]}
