The login handler discards the AuthnRequest ID and the callback validates the assertion without requiring a matching InResponseTo, so an unauthenticated attacker who can cause a victim to load a page can complete a SAML login in the victim's browser using the attacker's own assertion, silently logging the victim into the attacker's Airflow account. Subsequent work the victim performs lands in a session the attacker controls.\n\nAffects deployments using the AWS auth manager with SAML authentication. The victim needs only to visit an attacker-controlled page; no Airflow account or credential is required of the attacker. This is the same login-CSRF class fixed in the Keycloak auth manager as CVE-2026-40948.\n\nUsers of apache-airflow-providers-amazon are recommended to upgrade to version 9.38.0, which fixes the issue.","state":0,"publishedAt":"2026-10-20T02:37:07.184+00:00","modifiedAt":"2026-10-29T18:02:32.886+00:00","affected":[{"ecosystem":"https://pypi.python.org","name":"apache-airflow-providers-amazon","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache Airflow Amazon provider\",\n                    \"packageURL\": \"pkg:pypi/apache-airflow-providers-amazon\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"9.38.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"collectionURL\": \"https://pypi.python.org\",\n                    \"packageName\": \"apache-airflow-providers-amazon\"\n                }"}],"metrics":[],"references":["https://github.com/apache/airflow/pull/73698","https://lists.apache.org/thread/xr9d2jyk9qpglsmromt6vjl4s9jb5qn8","https://www.cve.org/CVERecord?id=CVE-2026-40948"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-86467","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-86467","identifiers":["CVE-2026-86467"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
