Vulnerability Title
Apache Airflow: API authorization bypass: bulk TaskInstances allows cross-DAG mutation
Source: CVE Program / CVE List V5
Vulnerability Description
A bug in Apache Airflow's bulk Task Instances API (`PATCH/DELETE /api/v2/dags/{dag_id}/dagRuns/{dag_run_id}/taskInstances`) evaluated authorization against the `dag_id` resolved from the URL path while operating on the `dag_id` / `dag_run_id` extracted from request-body entity fields. An authenticated UI/API user with edit permission on one Dag could mutate Task Instance state in any other Dag by keeping the authorized Dag's ID in the URL path and naming the target Dag's IDs in the request body entities. Affects deployments that rely on per-Dag edit-scope to keep Task Instance state isolated between teams. Users are advised to upgrade to `apache-airflow` 3.2.2 or later.

Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
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存在安全漏洞，该漏洞源于批量任务实例API在根据URL路径解析的dag_id评估授权的同时操作从请求体实体字段提取的dag_id/dag_run_id，可能导致经过身份验证的用户通过保持授权Dag的ID在URL路径中并在请求体实体中指定目标Dag的ID来修改其他Dag的任务实例状态。
