Vulnerability Title
Apache Airflow: Dags endpoint might provide access to otherwise inaccessible entities
Source: NVD (National Vulnerability Database)
Vulnerability Description
The authenticated /ui/dags endpoint did not enforce per-DAG access control on embedded Human-in-the-Loop (HITL) and TaskInstance records: a logged-in Airflow user with read access to at least one DAG could retrieve HITL prompts (including their request parameters) and full TaskInstance details for DAGs outside their authorized scope. Because HITL prompts and TaskInstance fields routinely carry operator parameters and free-form context attached to a task, the leak widens visibility of DAG-run data beyond the intended per-DAG RBAC boundary for every authenticated user. Users are recommended to upgrade to version 3.2.1 , which fixes this issue.

Vulnerability Title
Apache Airflow 安全漏洞
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 3.2.1之前版本存在安全漏洞，该漏洞源于/ui/dags端点未对嵌入的HITL和TaskInstance记录执行每DAG访问控制，可能导致具有至少一个DAG读取权限的经过身份验证的用户检索授权范围外的HITL提示和TaskInstance详细信息。
