{"schema":"threatline.record/2","record":{"id":"CVE-2026-94135","aliases":[],"summary":"Apache Airflow SFTP provider: Async SFTP hook disables host-key verification by default","details":"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.","categories":["Unclassified"],"product":"Apache Airflow SFTP provider","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94135","source_modified_at":"2026-10-16T14:46:22.385Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Apache Airflow SFTP provider","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"0","lessThan":"7.0.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94135","source_modified_at":"2026-10-16T14:46:22.385Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Apache Airflow SFTP provider","ecosystem":null},"version":"7.0.0","basis":"first unaffected version stated in the CVE record"}],"cvss":4.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.0022,"percentile":0.11845,"score_date":"2026-10-23"},"published_at":"2026-10-15T21:40:24.810Z","modified_at":"2026-10-16T14:46:22.385Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-94135","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T14:46:22.385Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-94135","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/apache/airflow/pull/73419","tags":["patch"]},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-94134","tags":["related"]},{"source":"CVE List","url":"https://lists.apache.org/thread/jbzs97t9y1zd1yp5rvxzjbx90mqz82kf","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-16T14:46:17.150791Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T14:46:22.385Z","content_hash":"55c0b070065dd7702833890640fc8c04837fcd8b1770379dd4bed7849091e7ca"}}
