Vulnerability Title
Arbitrary local file read via XSD `schemaLocation` (`xs:include`/`xs:import`) path traversal, with no remote-ref gate
Source: CVE Program / CVE List V5
Vulnerability Description
datamodel-code-generator generates Python data models from schema definitions. From 0.59.0 until 0.62.0, XML Schema parsing in src/datamodel_code_generator/parser/xmlschema.py for --input-file-type xmlschema resolves xs:include, xs:import, xs:redefine, and xs:override schemaLocation values outside the input base path, allowing arbitrary local files to be read and reflected into generated models. This issue is fixed in version 0.62.0.

Vulnerability Title
Koudai Aono datamodel-code-generator 信息泄露漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Koudai Aono datamodel-code-generator是日本Koudai Aono个人开发者的一款数据模型代码生成器。 Koudai Aono datamodel-code-generator 0.59.0版本至0.62.0之前版本存在安全漏洞，该漏洞源于XML Schema解析时未正确限制xs:include、xs:import、xs:redefine和xs:override的schemaLocation路径，允许读取任意本地文件并反映到生成的模型中。
