# CVE-2026-96806

> 5.8 MEDIUM · 🧪 PoC

## Beschreibung

The Apache Airflow Keycloak auth manager did not end the session on logout: the logout route revoked the presented token, but `KeycloakJWTMiddleware` then issued a new, unrevoked token on the same response, so the user stayed logged in. Deployments using the Keycloak auth manager are affected: after a user logs out, anyone with later access to the same browser (for example on a shared workstation) can continue to act as that user.

Users of apache-airflow-providers-keycloak are recommended to upgrade to apache-airflow-providers-keycloak 0.11.1 or later.
