CVE-2026-55390: Koxudaxi Datamodel-Code-Generator

High severity, CVSS 7.5. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Koxudaxi Datamodel-Code-Generator: from 0.59.0, before 0.62.0 (fixed in 0.62.0)
