CVE-2026-54662
CVE-2026-54662 · swagger-typescript-api vulnerable to code injection via unescaped `servers[0].url` in fetch http-client template
This page contains facts from public vulnerability sources. Check the original advisory before updating.
swagger-typescript-api generates API clients for Fetch or Axios from OpenAPI specifications. Prior to 13.12.2, src/code-gen-process.ts createApiConfig copies servers[0].url into apiConfig.baseUrl, and templates/base/http-clients/fetch-http-client.ejs interpolates apiConfig.baseUrl into the generated HttpClient baseUrl field without escaping, allowing an attacker-controlled OpenAPI spec to inject TypeScript static field code that executes when the generated fetch client module is imported. This issue is fixed in version 13.12.2.
