AI-suggested

Upgrade to datamodel-code-generator version 0.63.0 or later, where this vulnerability is fixed. No other mitigation is indicated or required.

Description

datamodel-code-generator generates Python data models from schema definitions. Prior to 0.63.0, src/datamodel_code_generator/http.py get_body reuses Authorization, Cookie, and Proxy-Authorization headers when following cross-origin redirects while fetching remote schemas, allowing credentials scoped to one schema host to be leaked to another redirect target. This issue is fixed in version 0.63.0.
