Description
swagger-typescript-api generates API clients for Fetch or Axios from an OpenAPI Specification. Prior to 13.12.2, templates/base/http-clients/axios-http-client.ejs interpolates servers[0].url from src/code-gen-process.ts into the HttpClient constructor without escaping, allowing an attacker-controlled OpenAPI spec to inject code that executes when new HttpClient() or new Api() is constructed. This issue is fixed in version 13.12.2.
