CVE-2026-96806Apache Airflow Keycloak provider: Keycloak auth manager: logout does not invalidate the session — JWTMiddleware mints an unrevoked replacement token
Medium 5.8
In plain English
A medium-severity security flaw in Apache Airflow Keycloak provider from Apache Software Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 31% of all known vulnerabilities).
Official description
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.
