Quick assessment

Affected
Apache Software Foundation Apache Airflow FAB provider
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 Software Foundation Apache Airflow FAB provider是Apache Software Foundation基金会的任务调度与编排平台的定义组件。 Apache Airflow FAB provider 3.7.2之前版本存在权限许可和访问控制问题漏洞，该漏洞源于资源名称冲突，可能导致拥有特定DAG访问权限的低权限用户被授予全局所有DAG的读取/编辑权限，实现权限提升。

Vulnerability Title
Apache Airflow FAB provider: FAB auth manager: a DAG named "DAGs" hijacks the global all-DAGs permission (access_control privilege escalation via resource_name() collision)
Source: CVE Program / CVE List V5
Vulnerability Description
In the Apache Airflow FAB auth manager, a DAG whose `dag_id` is `DAGs` collided with the global all-DAGs permission resource name produced by `resource_name()`, so a user granted per-DAG `access_control` on that one DAG was silently granted the global all-DAGs permission (privilege escalation). The escalation triggers when a DAG named `DAGs` exists and a lower-privileged user is given per-DAG access to it, granting that user read/edit access to every DAG. Users are advised to upgrade to `apache-airflow-providers-fab` 3.7.2 or later, which disambiguates the resource-name collision.
