The Keycloak authentication manager in "apache-airflow-providers-keycloak" did not generate or validate the OAuth 2.0 "state" parameter on the login / login-callback flow, and did not use PKCE. An attacker with a Keycloak account in the same realm could deliver a crafted callback URL to a victim's browser and cause the victim to be logged into the attacker's Airflow session (login-CSRF / session fixation), where any credentials the victim subsequently stored in Airflow Connections would be harvestable by the attacker. Users are advised to upgrade "apache-airflow-providers-keycloak" to 0.7.0 or later.
