Apache Airflow: Auth manager doesn't invalidate JWT tokens after users click logout

CVE-2026-48726 [CRITICAL] CWE-613 Apache Airflow: Auth manager doesn't invalidate JWT tokens after users click logout
Apache Airflow: Auth manager doesn't invalidate JWT tokens after users click logout
A bug in Apache Airflow's auth manager logout handling left previously-issued JWT tokens valid after the user clicked logout in the UI: the logout flow for `FabAuthManager` and `KeycloakAuthManager` did not actually reach the underlying `revoke_token()` call, so the JWT remained accepted by the API server until its natural expiry. An attacker holding a previously-issued JWT for a logged-out user could continue to make authenticated API calls as that user. Affects deployments configured with `FabAuthManager` or `KeycloakAuthManager` (the bug does not affect SimpleAuthManager). This is a residual gap in the fix for CVE-2025-57735, which addressed cookie-side invalidation in PR #57992 / PR #61339 but did not
