{"cve":"CVE-2026-41017","nvd":{"published":"2026-06-01T09:16:18.343","modified":"2026-07-21T19:10:00.107","status":"Modified","description":"Apache Airflow's `JWTRefreshMiddleware` set the JWT auth cookie without the `Secure` flag, so deployments running the Airflow API server behind an HTTPS-terminating reverse proxy (e.g. nginx / Envoy / a managed load balancer that terminates TLS and forwards plaintext to the API server, the default cloud-native topology) would have the user's session JWT replayed over any cleartext HTTP request to the same host. A network-positioned attacker (Wi-Fi MITM, hostile LAN, captive-portal proxy) could induce a logged-in user's browser to issue an HTTP request to the deployment's hostname and capture the JWT cookie out of that request, then replay it against the authenticated API. Affects deployments where the Airflow API server is reached through a TLS-terminating proxy and the cookie's secure-by-default protection is load-bearing for session integrity. Users are advised to upgrade to `apache-airflow` 3.2.2 or later.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9},"cwes":["CWE-614"],"references":["https://github.com/apache/airflow/pull/65348","https://lists.apache.org/thread/9jx0sk49c1250zflx0q3clc717qgjdch","http://www.openwall.com/lists/oss-security/2026/05/31/6"],"products":["apache:airflow"],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-41017","score":0.0035,"percentile":0.287,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-95v7-h9j5-gvjr","url":"https://osv.dev/vulnerability/GHSA-95v7-h9j5-gvjr","summary":"Apache Airflow has a Sensitive Cookie in HTTPS Session Without 'Secure' Attribute","modified":"2026-07-09T21:11:15.586410293Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":[">=3.0.0 <3.2.2"],"fixed":["3.2.2"]}]},{"id":"PYSEC-2026-171","url":"https://osv.dev/vulnerability/PYSEC-2026-171","summary":"","modified":"2026-07-13T16:45:11.328047036Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow","purl":"pkg:pypi/apache-airflow","ranges":[">=3.0.0 <3.2.2"],"fixed":["3.2.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
