Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Airflow (apache-airflow) versions 3.0.0 before 3.2.2 set the JWT auth cookie without the Secure flag, so the cookie could be sent over plaintext HTTP in deployments where a reverse proxy terminates TLS in front of the API server. An attacker on the network path, such as someone performing a man-in-the-middle attack on Wi-Fi, could induce a logged-in user's browser to send an HTTP request to the deployment's hostname, capture the JWT cookie, and replay it against the API. Upgrade to apache-airflow 3.2.2 or later.
