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 的 CeleryExecutor 在运行回调工作负载（ ，用于触发期限提醒回调）时，未对工作负载的身份验证令牌进行验证。任何能够向 Celery 消息代理写入数据的攻击者，均可注入伪造的回调任务，从而在无需 Airflow 凭据的情况下，在所有 CeleryExecutor 工作节点上执行任意代码。此漏洞影响所有使用 CeleryExecutor 的部署环境。 建议用户升级至 apache-airflow 3.4.0 或更高版本。在该版本中，工作节点在运行回调前，会通过执行 API（E

Vulnerability Title
Apache Airflow: CeleryExecutor: forged callback workloads run on Celery workers without workload-token validation
Source: CVE Program / CVE List V5
Vulnerability Description
Apache Airflow's CeleryExecutor ran callback workloads (`ExecuteCallback`, used for deadline-alert callbacks) without validating the workload's authentication token. Anyone able to write to the Celery broker could enqueue a forged callback and execute arbitrary code on every CeleryExecutor worker, without Airflow credentials. Deployments using the CeleryExecutor are affected. Users are advised to upgrade to apache-airflow 3.4.0 or later, in which the worker claims the callback through the Execution API, validating the token, before running it.
