Scan Your Supabase AppCommon Security Issues in Supabase Apps
Exposed API Keys
AI coding tools often embed API keys directly in frontend JavaScript. If you're using Supabase, 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Outdated npm packages with known CVEs are common in AI-generated code.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.
