{"id":"CVE-2026-58065","state":"PUBLISHED","title":"Apache Airflow Git provider: Git provider hook defaults to StrictHostKeyChecking=no, disabling SSH host-key verification","description":"The Apache Airflow Git provider runs its git-over-SSH operations with `StrictHostKeyChecking=no` by default, disabling SSH host-key verification. An attacker who can intercept the network path between an Airflow worker and the Git server can impersonate the server (man-in-the-middle), capturing the SSH deploy key or injecting malicious repository content. Deployments that use the Git DAG bundle or Git provider to clone over SSH with a deploy key are affected. The fix changes the default to verify host keys; upgrade to apache-airflow-providers-git `0.4.1` or later and configure a `known_hosts` file.","publishedAt":"2026-07-13T15:00:49.159Z","updatedAt":"2026-09-16T15:06:43.587Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"CISA-ADP"},"assigner":"apache","products":["Apache Software Foundation Apache Airflow Git provider"],"affected":[{"vendor":"Apache Software Foundation","product":"Apache Airflow Git provider","packageName":"apache-airflow-providers-git","packageURL":"pkg:pypi/apache-airflow-providers-git","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"0.4.1","versionType":"semver"}],"collectionURL":"https://pypi.python.org"}],"references":["https://github.com/apache/airflow/pull/69103","https://lists.apache.org/thread/fjmclngfksz2kp7llpcjxzdz568h0zhc","http://www.openwall.com/lists/oss-security/2026/07/13/3"],"weaknesses":["CWE-322"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/58xxx/CVE-2026-58065.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-58065","state":"PUBLISHED","datePublished":"2026-07-13T15:00:49.159Z","dateUpdated":"2026-09-16T15:06:43.587Z","assignerShortName":"apache","assignerOrgId":"f0158376-9dc2-43b6-827c-5f631a4d8d09","dateReserved":"2026-06-28T14:39:59.245Z"},"containers":{"cna":{"title":"Apache Airflow Git provider: Git provider hook defaults to StrictHostKeyChecking=no, disabling SSH host-key verification","descriptions":[{"lang":"en","value":"The Apache Airflow Git provider runs its git-over-SSH operations with `StrictHostKeyChecking=no` by default, disabling SSH host-key verification.
