Description

Apache Airflow versions 3.1.0 through 3.1.7 session token (_token) in cookies is set to path=/ regardless of the configured [webserver] base_url or [api] base_url.<br /> This allows any application co-hosted under the same domain to capture valid Airflow session tokens from HTTP request headers, allowing full session takeover without attacking Airflow itself.<br /> <br /> Users are recommended to upgrade to Apache Airflow 3.1.8 or later, which resolves this issue.
