CVE-2026-54655
`datamodel-code-generator` vulnerable to code execution on import via `x-python-type` JSON-Schema extension in datamodel-code-generator
CVSS Score
7.8
EPSS Score
0.0%
EPSS Percentile
0th
datamodel-code-generator generates Python data models from schema definitions. From 0.51.0 until 0.60.2, x-python-type values parsed by src/datamodel_code_generator/parser/jsonschema.py in _get_python_type_override are inserted into generated field annotations without sufficient validation, allowing attacker-controlled JSON Schema content to execute Python code when the generated module is imported. This issue is fixed in version 0.60.2.
