Vercel 宣布其 Web 應用程式防火牆（WAF）現在支援管理 Next.js 的 Server Actions。開發者可以直接在 Vercel Firewall 中針對 Server Actions 的 POST 請求設定安全規則與速率限制（Rate Limiting），有效防止惡意調用、DDoS 攻擊及資源濫用，進一步鞏固全端 Next.js 應用的安全性。
Next.js Server Actions are a powerful feature that allows developers to call server-side functions directly from client components, greatly simplifying the full-stack development workflow. However, this convenience also brings security challenges: Server Actions are compiled under the hood into specific HTTP POST request endpoints. Without proper protection, these hidden endpoints are easily targeted by automated scripts for malicious traffic flooding, DDoS attacks, or unauthorized invocations, which can exhaust server resources or generate high Vercel bills.
