swagger-typescript-api generates API clients for Fetch or Axios from OpenAPI specifications. Prior to 13.12.2, src/resolved-swagger-schema.ts getRemoteRequestHeaders forwards --authorizationToken to every URL fetched by fetchRemoteSchemaDocument while warmUpRemoteSchemasCache resolves external $ref URLs, allowing an attacker-controlled OpenAPI spec to exfiltrate the developer or CI bearer token to a cross-origin endpoint. This issue is fixed in version 13.12.2.
