An API key embedded in client-side JavaScript gives anyone with a browser devtools tab full access to your cloud services, databases, or third-party APIs — leading to data breaches, unexpected charges, or account takeover.

Check for common patterns like sk_, pk_, AIza, ghp_, AKIA, and base64-encoded strings in unusual contexts.
Move all secrets server-side. Replace client-exposed credentials with server-side API proxies. Rotate any leaked credentials immediately — treat them as compromised. Implement git-secrets or a pre-commit hook to prevent future leaks.
Explain why client-side JavaScript is public code, how secrets leak into bundles, what the impact of a leaked API key is, and how to architect applications to keep secrets server-side.
Review server config, headers, forms, and integration points related to Leaked Environment Variables. Flag exact responses, cookies, or browser behaviors that violate the rule, and verify them against the effective production-like response.
