CVE-2026-55415 – datamodel-code-generator vulnerable to code injection via `x-python-import` / `customTypePath` in generated import statements

CVE ID :CVE-2026-55415

Published : July 28, 2026, 10:17 p.m. | 22 minutes ago

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.

Severity: 7.5 | HIGH
