Exploitation
Public or AI PoC available; prioritize validation
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

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 0.11.6版本至0.64.0之前版本存在代码注入漏洞，该漏洞源于允许攻击者控制的x-python-import或customTypePath schema扩展，通过Import.from_full_path和Imports.create_line处理，导致可执行Python代码。

Vulnerability Title
datamodel-code-generator vulnerable to code injection via `x-python-import` / `customTypePath` in generated import statements
Source: CVE Program / CVE List V5
Vulnerability Description
datamodel-code-generator generates Pydantic v2 models, dataclasses, TypedDict, and msgspec.Struct from OpenAPI, JSON Schema, GraphQL, Avro, Protobuf, and raw JSON, YAML, or CSV. From 0.11.6 until 0.64.0, datamodel-code-generator allows attacker-controlled x-python-import or customTypePath schema extensions to reach src/datamodel_code_generator/parser/jsonschema.py and generated import handling through Import.from_full_path and Imports.create_line in src/datamodel_code_generator/imports.py, allowing a newline to break out of an import statement and execute Python code when the generated model is imported. This issue is fixed in version 0.64.0.
