DescriptionCVE.org

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.

AnalysisAI

Arbitrary local file read in datamodel-code-generator versions 0.59.0 to 0.61.0 via path traversal in XSD parsing allows unauthenticated attackers who control an input XML Schema to read any file readable by the generator process, with the contents reflected into generated models. A public proof-of-concept exploit exists, and the issue is fixed in version 0.62.0.
