Serverless Forms: Protecting Customer Data Without Vulnerable Plugins

The Vulnerability of Contact Forms

On a traditional LAMP stack, contact forms are processed by PHP. The user submits data, PHP parses it, and often saves it directly into the WordPress SQL database before sending an email.

This process is highly vulnerable to Cross-Site Scripting (XSS) and SQL Injection attacks. It’s also a massive target for spam bots.

The Serverless Solution

At AlaskaWeb.pro, we handle form submissions using Cloudflare Workers and Serverless edge functions.

1. The Static Form: The form itself is rendered as pure HTML, with zero server-side logic attached to the page.
2. The Secure Edge Endpoint: When a user clicks submit, the data is sent to an isolated, serverless function running on the edge.
3. Instant Validation and Routing: The function validates the data, checks a non-intrusive Turnstile token (blocking bots without annoying CAPTCHAs), and routes the data directly to your CRM or email provider via a secure API.

The data is never stored in a vulnerable local database. This approach ensures maximum security and strict compliance with data protection regulations.
