Replit Secrets and the stripe secret key that ended up in your bundle

Why Replit does this

Replit Secrets are injected as environment variables at build time. A secret that gets a `VITE_` prefix so the frontend can "see" it stops being a secret — the prefix is the mechanism that copies it into the bundle.

Confirm it first

Before rotating anything, check whether the key is actually being served. Paste your deployed URL — KeyDrift downloads the same JavaScript a visitor gets and tells you what is in it.

Rotate the key

Do this before changing any code. The key has been served to browsers, cached by CDNs and very likely scraped already — removing it from the source does not un-publish it.

1. 1Roll the key in the Stripe dashboard. Rolling issues a replacement and revokes the old key.
2. 2Review recent charges, refunds and payouts for anything you did not initiate.
3. 3Move the Stripe call into a server route. The browser only ever needs the publishable key.

Move the call to a server

The replacement key must not follow the old one into the bundle, which means the code that uses it cannot live in the browser. Any variable named VITE_… is inlined at build time by design — the prefix is the mechanism, not a mistake.

// src/components/Chat.tsx
// Vite substitutes the literal value here at build time.
const key = import.meta.env.VITE_STRIPE_SECRET_KEY;
const result = await new Stripe(key).checkout.sessions.create(body);

// supabase/functions/checkout/index.ts  — runs on the Express server in the same Repl
Deno.serve(async (request) => {
  const key = Deno.env.get('STRIPE_SECRET_KEY')!; // never sent to the browser
  const result = await new Stripe(key).checkout.sessions.create(body);
  return Response.json(result);
});

// src/components/Chat.tsx
const result = await fetch('/functions/v1/checkout', { method: 'POST' }).then((r) => r.json());

How KeyDrift detects it

Matches `sk_live_` and `sk_test_`, then reads the surrounding code. Clerk issues secret keys in exactly this format and nothing in the string distinguishes them, so when only Clerk is referenced nearby the finding is attributed to Clerk, when both are the finding names both, and a `sk_test_` key is reported at medium because no real money can move.
