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.
