Live Secret in JS Check — Is a Real Key in the JavaScript Your Site Serves?
DevMeth checks the 48 known AI-code failure patterns — not a penetration test or a security guarantee.
What the issue is
Even if source looks fine, the JavaScript your deployed site actually serves to anyone can contain a live secret — from a public env prefix, a hardcoded value, or a config that leaked into the build.
Why AI tools generate it
A build or config step can bake a working key into the bundle the server outputs, so the deployed artifact differs from the source on disk.
How DevMeth detects it
A live probe fetches your site's JavaScript the way any visitor can and scans it for secret-shaped values, reporting masked matches.
A live secret is visible in the JavaScript your site serves to anyone
WHAT WE FOUND
/_next/static/chunks/main.js — sk-…a1b2 (masked)
The fix, in three steps
Find where the value enters the build, rotate it, move it to a server-only secret, and redeploy so the served bundle is clean. Three steps.
Run a free scan and each finding carries a paste-ready fix prompt you can act on.

Why check the live site and not just source?
Because the deployed bundle is what attackers actually see. A build step can leak a key into served JS even when source looks clean.
What does the probe fetch?
It fetches your site's JavaScript bundles read-only, the same way any visitor would, and scans them for secret-shaped values.
Is the secret ever shown in full?
Never. Findings show only a masked prefix and last 4 characters.
