Nest has a Fastify URL Encoding Middleware Bypass (TOCTOU)

Nest is a framework for building scalable Node.js server-side applications. Versions prior to 11.1.11 have a Fastify URL encoding middleware bypass. A NestJS application is vulnerable if it uses `@nestjs/platform-fastify`; relies on `NestMiddleware` (via `MiddlewareConsumer`) for security checks (authentication, authorization, etc.), or through `app.use()`; and applies middleware to specific routes using string paths or controllers (e.g., `.forRoutes('admin')`). Exploitation can result in unauthenticated users accessing protected routes, restricted administrative endpoints becoming accessible to lower-privileged users, and/or middleware performing sanitization or validation being skipped. This issue is patched in `@nestjs/platform-fastify@11.1.11`.

nest 安全漏洞

nest是nestjs开源的一个 Node.js 框架，用于使用 TypeScript/JavaScript 构建高效、可扩展和企业级的服务器端应用程序。 nest 11.1.11之前版本存在安全漏洞，该漏洞源于Fastify URL编码中间件存在绕过，可能导致未经验证的用户访问受保护路由。
