CVE-2026-96806: Apache Airflow Keycloak provider: Keycloak auth manager: logout does not invalidate the session — JWTMiddleware mints an unrevoked replacement token

• Severity: medium (CVSS 5.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-10-15 · updated 2026-10-16
• Weakness: CWE-613

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.

Affected products

• Apache Software Foundation Apache Airflow Keycloak provider: before 0.11.1 — fixed in 0.11.1

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache Airflow Keycloak provider 0.11.1. Check the vendor advisory for mitigations.
