Missing Content Security Policy

Your website doesn't have a Content Security Policy (CSP) header. This header tells the browser which resources are safe to load.

Why This Matters

Without a CSP, attackers who find a way to inject code into your site can load malicious scripts, steal data, or trick users. CSP acts as a safety net that limits what can run on your pages.

How to Fix
Framework-specific solutions and general best practices

Add a Content-Security-Policy header to your server responses. Start with a basic policy like: "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline';" and adjust based on your needs.
