Any deployment using `FTPSHook` or `FTPSFileTransmitOperator` to move files over FTPS exposed file contents and credentials-in-transit to a network attacker able to observe the data connection. Upgrade apache-airflow-providers-ftp to `3.15.1` or later, which issues `PROT P` to encrypt the data channel.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-319"],"references":["https://github.com/apache/airflow/pull/67946","https://lists.apache.org/thread/gwnsxlt9hfj5pc543wxtogbnjdn04xj1","http://www.openwall.com/lists/oss-security/2026/06/26/1"],"products":["apache:apache-airflow-providers-ftp"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-49486","score":0.00442,"percentile":0.38165,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-fgch-86x8-fv43","url":"https://osv.dev/vulnerability/GHSA-fgch-86x8-fv43","summary":"Apache Airflow FTP provider: FTP Provider does not protect FTPS data channel (missing PROT_P)","modified":"2026-09-10T03:50:49.336726240Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow-providers-ftp","purl":"pkg:pypi/apache-airflow-providers-ftp","ranges":["<3.15.1"],"fixed":["3.15.1"]}]},{"id":"PYSEC-2026-238","url":"https://osv.dev/vulnerability/PYSEC-2026-238","summary":"","modified":"2026-09-10T11:15:08.166976325Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow-providers-ftp","purl":"pkg:pypi/apache-airflow-providers-ftp","ranges":["<3.15.1"],"fixed":["3.15.1"]}]}],"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).
