Every finding comes with a fix prompt

You don't need to know what a CSP is. Copy the prompt, paste it into your AI tool, re-scan to green.

Stripe secret key found in client-side JavaScript

A live secret key (sk_live_…) is readable by anyone who opens your site's JS bundle. With it, an attacker can charge cards and issue refunds as you.

AI fix prompt
My app has a Stripe secret key (sk_live_...) exposed in the client bundle at /static/js/main.js. Move all Stripe secret key usage to server-side code (an API route or server function), replace any client-side usage with the publishable key, move the secret into an environment variable, and remind me to rotate the compromised key in the Stripe dashboard.
Paste into Cursor, Claude Code, or your AI tool of choice.
