CVE-2026-48726— Apache Airflow: revoke_token() unreachable in FabAuthManager / KeycloakAuthManager logout path

Quick assessment

Affected
Apache Software Foundation Apache Airflow
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Airflow是美国阿帕奇（Apache）基金会的一套具有创建、管理和监控工作流程功能的开源平台。该平台具有可扩展和动态监控等特点。 Apache Airflow 3.2.2之前版本存在代码问题漏洞，该漏洞源于认证管理器注销处理中未调用撤销令牌函数，可能导致之前颁发的JWT令牌在用户注销后仍然有效。

Vulnerability Title
Apache Airflow: revoke_token() unreachable in FabAuthManager / KeycloakAuthManager logout path
Source: CVE Program / CVE List V5
Vulnerability Description
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 cover the provider-side `revoke_token()` reachability in the FAB / Keycloak code paths. Users who already upgraded for CVE-2025-57735 should additionally upgrade to `apache-airflow` 3.2.2 or later to cover the FAB / Keycloak logout paths.
