Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Recommended fix High confidence

apache-airflow 3.2.2 or later (latest 3.2.x release)

  1. 1. Review the current apache-airflow version in your environment using your package manager or dependency file (e.g., pip show apache-airflow, requirements.txt, or your deployment configuration).
  2. 2. Stop any running Airflow services to prevent disruption during the upgrade.
  3. 3. Upgrade apache-airflow to version 3.2.2 or later using your package manager. For pip, run: pip install 'apache-airflow>=3.2.2' or pip install --upgrade apache-airflow (which will install the latest version).
  4. 4. Verify the upgrade was successful by checking the installed version: pip show apache-airflow.
  5. 5. Review the Airflow 3.2.2 release notes for any configuration changes or migration steps required.
  6. 6. Restart Airflow services and verify that the application functions correctly with the new version.
  7. 7. For deployments using a TLS-terminating reverse proxy, confirm that the JWT cookie is now being set with the Secure flag by inspecting HTTP responses from the Airflow API server.
