Vibe-Coded App Security

You built your SaaS with AI code generation. It shipped fast. It also broke in ways hand-written code does not.

AI-assisted code fails along its own fault lines. The same pattern-matching that makes generation fast puts credentials in the wrong place, writes row-level security policies that look correct and are not, and confidently imports a package that does not exist until an attacker registers the name.

This is a 70-page field guide to the specific failures, each one paired with the fix.

Chapters:

* Why vibe-coded apps break differently than hand-written code

* Hardcoded secrets, the most common critical mistake

* Supabase row level security and the silent data exposure

* Slopsquatting: when your AI hallucinates a package name an attacker already owns

* Unauthenticated admin endpoints

* Prompt injection: when user input hijacks your AI features

* Authentication gaps in sessions, tokens and broken flows

* Insecure file uploads and storage misconfiguration

* A CLAUDE.md security rules template you can paste into your repo

* A 25-point pre-launch audit checklist

* An incident response card for the day you get hacked

* Building security into the vibe-coding workflow so this does not recur

Written for solo founders and small teams who ship with AI assistance and do not have a security engineer to ask.
