{"schema":"threatline.record/2","record":{"id":"CVE-2026-94134","aliases":[],"summary":"Apache Airflow SSH provider, Apache Airflow SFTP provider: SSH hook disables host-key verification by default","details":"The Apache Airflow SSH provider hook disables SSH host-key verification by default: unless `host_key` is configured or `no_host_key_check` is explicitly set to false, it accepts any server key. This affects SSH and SFTP connections that rely on the default. An attacker in a machine-in-the-middle position between the worker and the SSH or SFTP server can impersonate the server and capture the credentials or data a task sends.\n\nUsers of apache-airflow-providers-ssh and apache-airflow-providers-sftp are recommended to upgrade to apache-airflow-providers-ssh 7.0.0 and apache-airflow-providers-sftp 7.0.0 or later. The deferrable SFTP code paths had the same default and are covered separately by CVE-2026-94135; apache-airflow-providers-sftp 7.0.0 fixes both.","categories":["Unclassified"],"product":"Apache Airflow SSH provider","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94134","source_modified_at":"2026-10-16T14:53:59.032Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Apache Airflow SSH provider","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"0","lessThan":"7.0.0","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94134","source_modified_at":"2026-10-16T14:53:59.032Z","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-2026-94134","source_modified_at":"2026-10-16T14:53:59.032Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Apache Airflow SSH provider","ecosystem":null},"version":"7.0.0","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-94134","source_modified_at":"2026-10-16T14:53:59.032Z","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":9.1,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.003,"percentile":0.21541,"score_date":"2026-10-23"},"published_at":"2026-10-15T21:39:03.081Z","modified_at":"2026-10-16T14:53:59.032Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-94134","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T14:53:59.032Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-94134","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-2026-94135","tags":["related"]},{"source":"CVE List","url":"https://lists.apache.org/thread/ksr1lztvd3zr74f8xd1hzch1ssl0l3lj","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-16T14:53:40.519965Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T14:53:59.032Z","content_hash":"bae73984ee4377c2790526a51df706e5fa8140133ef778d02fbd172ffcb8b0ab"}}
