CVE-2026-96806: Apache Software Foundation Apache Airflow Keycloak Provider

Medium severity, CVSS 5.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Apache Software Foundation Apache Airflow Keycloak Provider: before 0.11.1 (fixed in 0.11.1)
