Vulnerability Title
Ray: Remote Code Execution via Parquet Arrow Extension Type Deserialization
Source: NVD (National Vulnerability Database)
Vulnerability Description
Ray is an AI compute engine. From version 2.54.0 to before version 2.55.0, Ray Data registers custom Arrow extension types (ray.data.arrow_tensor, ray.data.arrow_tensor_v2, ray.data.arrow_variable_shaped_tensor) globally in PyArrow. When PyArrow reads a Parquet file containing one of these extension types, it calls __arrow_ext_deserialize__ on the field's metadata bytes. Ray's implementation passes these bytes directly to cloudpickle.loads(), achieving arbitrary code execution during schema parsing, before any row data is read. This issue has been patched in version 2.55.0.

Ray 代码注入漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Ray是ray-project开源的一个用于扩展 AI 和 Python 应用程序的统一框架。 Ray 2.54.0版本至2.55.0之前版本存在代码注入漏洞，该漏洞源于全局注册自定义Arrow扩展类型时，PyArrow读取Parquet文件调用__arrow_ext_deserialize__，可能导致在模式解析期间执行任意代码。
