Render API key in your client bundle

What this rule means

A string matching rnd_* was found in your deployed JavaScript.

Why it matters

Service deploys, env vars, billing. Automated scrapers harvest these keys from public bundles within hours; assume the key is compromised the moment it shipped.

How to fix it

  1. Revoke the key immediately at https://dashboard.render.com/u/settings.
  2. Move the new key to server-only env vars. Never use a name with the NEXT_PUBLIC_, VITE_, or PUBLIC_ prefix.
  3. Pattern your calls as client → your API → Render. Never client → Render directly.
  4. Set a spend or rate limit in the Render console as a safety net.
  5. Add a CI gate to fail any future deploy that includes the key pattern: vibecheck https://your-deploy.com --exit-on critical.

Did vibecheck flag this on your app?

If you reached this page from a vibecheck inspection report, the redacted match in your scan output is the exact string we found in your bundle. After applying the fix above, run the inspection again — the finding should clear.
