Escape.tech scanned 5,600 vibe-coded apps and found 2,000+ vulnerabilities and 400 exposed secrets. Tenzai tested 15 apps across 5 AI coding tools and found 69 vulnerabilities. CodeRabbit found AI-written code introduces 2.74x more XSS vulnerabilities than human-written code. The pattern is always the same: exposed API keys, missing database security policies, open API routes, no rate limiting. The worst part? These are all fixable. Most in under 15 minutes.

Exposed Secrets in Source Code Every vibe-coded app I scanned had at least one instance of credentials in the codebase. .env files committed to git. Firebase config objects wit
