v0 Security Audit
Built your app with v0? We find the security issues AI missed.
v0 by Vercel specialises in generating frontend React components and page layouts from natural language descriptions. It excels at producing visually polished UI code using Tailwind CSS and shadcn/ui. However, its focus on appearance over architecture means the generated code often lacks proper authentication guards, data sanitisation, and secure state management patterns.
Common v0 Security Issues
These are the vulnerabilities we most frequently find in v0-generated projects.
Client-side only authentication checks
criticalv0 generates auth guards that only run in the browser using conditional rendering, which can be bypassed by directly hitting API routes or manipulating client state.
Unescaped user content rendering
highGenerated components frequently use dangerouslySetInnerHTML or fail to sanitise user-provided content before rendering, opening the door to XSS attacks.
Hardcoded demo data patterns
mediumv0 often scaffolds components with hardcoded arrays and mock data that developers forget to replace, leading to placeholder credentials or test API endpoints shipping to production.
Missing loading and error states
mediumData fetching code lacks proper error boundaries and loading states, which can expose raw error objects to users or cause the app to crash ungracefully.

v0 Audit FAQ
Is v0 code secure?
v0 generates functional code quickly, but like all AI coding tools, it often prioritises getting things working over security best practices. Common issues include exposed API keys, missing input validation, and insecure database configurations. Our audits specifically target the patterns v0 tends to produce.
What are common v0 security issues?
The most frequent issues we find in v0 projects include: client-side only authentication checks, unescaped user content rendering, hardcoded demo data patterns. These are well-documented patterns that our audit process specifically checks for.
Do I need an audit for my v0 app?
If your v0 app handles user data, payments, or any sensitive information, an audit is strongly recommended before going to production. Even simple apps can have critical vulnerabilities that AI tools introduce without warning. Our Security Scan package is a great starting point.
How long does a v0 audit take?
Our Security Scan takes 3 business days, the Full Audit takes 7 business days, and the Production Ready package takes 10-12 business days. The timeline depends on the size and complexity of your codebase, not which tool generated it.
