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."

Antes de 0.63.0, src/datamodel_code_generator/http.py get_body reutiliza los encabezados de autorización, cookie y Proxy-Authorization al seguir redirecciones de origen cruzado mientras se recuperan esquemas remotos, permitiendo que las credenciales con ámbito a un host de esquema se filtren a otro objetivo de redirección. Este problema está solucionado en la versión 0.63.0."
