Several security risks are present. The `chatgpt-apps-sdk-nextjs-starter/middleware.ts` sets `Access-Control-Allow-Origin: *`, which is a critical vulnerability allowing any domain to access resources, making it unsafe for production. Recipient wallet addresses in `x402-mcp/index.ts` and `cronos-weather-server/index.ts` are hardcoded placeholders, which require user modification for actual deployment. The `NextChatSDKBootstrap` in `chatgpt-apps-sdk-nextjs-starter/app/layout.tsx` patches core browser APIs (`history.pushState`, `window.fetch`) and observes HTML attributes via an inline script. While justified for ChatGPT iframe compatibility, such low-level global API manipulation is a dangerous pattern that can be fragile and a source of vulnerabilities if not meticulously managed, and its behavior could be exploited if the host environment or inputs are compromised.
