Vulnerability in Apache (CVE-2026-96806)
Summary
Vulnerability in Apache (CVE-2026-96806). Risk of unauthorized operations or information disclosure. Exploitable via KeycloakJWTMiddleware.
Original description
The description as published by the source.
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.
