CVE-2026-41017— Apache Airflow: JWT cookie missing Secure flag in JWTRefreshMiddleware behind HTTPS-terminating proxy

Quick assessment

Affected
Apache Software Foundation Apache Airflow
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Airflow是美国阿帕奇（Apache）基金会的一套具有创建、管理和监控工作流程功能的开源平台。该平台具有可扩展和动态监控等特点。 Apache Airflow存在安全漏洞，该漏洞源于JWTRefreshMiddleware设置JWT认证cookie时未设置Secure标志，可能导致网络位置攻击者通过诱导已登录用户浏览器向部署主机名发出HTTP请求并捕获JWT cookie，然后重放攻击。

Vulnerability Title
Apache Airflow: JWT cookie missing Secure flag in JWTRefreshMiddleware behind HTTPS-terminating proxy
Source: CVE Program / CVE List V5
Vulnerability 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.
