CVE-2026-55390 – Arbitrary local file read via XSD `schemaLocation` (`xs:include`/`xs:import`) path traversal, with no remote-ref gate

CVE ID :CVE-2026-55390

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

Description :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.

Severity: 7.5 | HIGH
