Prior to 13.12.2, src/resolved-swagger-schema.ts warmUpRemoteSchemasCache resolves external $ref URLs and fetchRemoteSchemaDocument uses isHttpUrl to fetch any http or https target without private IP, redirect, DNS rebinding, or same-origin validation, allowing an attacker-controlled OpenAPI spec to make the generator issue requests to internal or link-local services. This issue is fixed in version 13.12.2."

Antes de la versión 13.12.2, src/resolved-swagger-schema.ts warmUpRemoteSchemasCache resuelve URLs $ref externas y fetchRemoteSchemaDocument usa isHttpUrl para obtener cualquier objetivo HTTP o HTTPS sin IP privada, redirección, reencadenamiento de DNS, o validación de mismo origen, permitiendo que una especificación OpenAPI controlada por un atacante haga que el generador emita solicitudes a servicios internos o de enlace local. Este problema está solucionado en la versión 13.12.2."
