{"schemaVersion":3,"id":"CVE-2026-94135","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"The Apache Airflow SFTP provider's deferrable code paths (`SFTPTrigger`, `SFTPHookAsync`, `SFTPClientPool`) disable SSH host-key verification by default unless the connection explicitly sets `no_host_key_check` to false. 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.","dates":{"published":"2026-10-15T21:40:24.810Z","modified":"2026-10-16T14:46:22.385Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":4.3,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":4.3,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":4.3,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.0022,"percentile":0.11625,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-16T00:00:00.000Z","score":0.00175,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0022,"percentile":0.11625}],"last30":[{"date":"2026-10-16T00:00:00.000Z","score":0.00175,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0022,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0022,"percentile":0.11625}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-322","name":"Key Exchange without Entity Authentication","description":"The product performs a key exchange with an actor without verifying the identity of that actor.","type":"weakness","status":"Draft","abstraction":"Base","likelihoodOfExploit":"High","url":"https://cwe.mitre.org/data/definitions/322.html"}],"affected":[{"vendor":"apache software foundation","product":"apache airflow sftp provider","name":"Apache Airflow SFTP provider","label":"apache airflow sftp provider","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"< 7.0.0","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 7.0.0","eol":null,"hubHref":"/vendor/apache_software_foundation/apache_airflow_sftp_provider"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/apache/airflow/pull/73419","label":"github.com/apache/airflow/pull/73419","hostname":"github.com","tags":["Patch"]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-94134","label":"www.cve.org/CVERecord?id=CVE-2026-94134","hostname":"www.cve.org","tags":["Related"]},{"url":"https://lists.apache.org/thread/jbzs97t9y1zd1yp5rvxzjbx90mqz82kf","label":"lists.apache.org/thread/jbzs97t9y1zd1yp5rvxzjbx90mqz82kf","hostname":"lists.apache.org","tags":["Vendor Advisory"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-15T21:40:24.810Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-16T14:46:22.385Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":17,"level":"low","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-19T00:53:01.600Z","stale":false,"partial":false}}
