Common Security Issues in Auth0 Apps

Exposed API Keys

AI coding tools often embed API keys directly in frontend JavaScript. If you're using Auth0, check that secret keys aren't in your client-side bundle.

Missing Security Headers

Headers like Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options protect against XSS, clickjacking, and downgrade attacks.

Vulnerable Dependencies

Outdated npm packages with known CVEs are common in AI-generated code. Regular audits catch these before attackers do.

Authentication Weaknesses

Open registration endpoints, missing rate limiting, and exposed auth tokens are frequent issues in vibe-coded apps.
