Deployments that run SFTP sensors or operators in deferrable mode are affected. An attacker in a machine-in-the-middle position between the triggerer and the SFTP server can impersonate the server and capture the credentials or data exchanged.\n\nUsers of apache-airflow-providers-sftp are recommended to upgrade to apache-airflow-providers-sftp 7.0.0 or later. This is a separate defect from CVE-2026-94134 (the synchronous SSH hook default, which also affects the SFTP hook); users who applied the fix for one also need this release for the other - apache-airflow-providers-sftp 7.0.0 fixes both.","state":0,"publishedAt":"2026-10-15T21:40:24.81+00:00","modifiedAt":"2026-10-16T14:46:22.385+00:00","affected":[{"ecosystem":"https://pypi.python.org","name":"apache-airflow-providers-sftp","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache Airflow SFTP provider\",\n                    \"packageURL\": \"pkg:pypi/apache-airflow-providers-sftp\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.0.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"collectionURL\": \"https://pypi.python.org\",\n                    \"packageName\": \"apache-airflow-providers-sftp\"\n                }"}],"metrics":[],"references":["https://github.com/apache/airflow/pull/73419","https://www.cve.org/CVERecord?id=CVE-2026-94134","https://lists.apache.org/thread/jbzs97t9y1zd1yp5rvxzjbx90mqz82kf"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-94135","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-94135","identifiers":["CVE-2026-94135"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
