Common Security Issues in v0 Apps

Exposed API Keys

AI coding tools often embed API keys directly in frontend JavaScript. If you're using v0, 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Outdated npm packages with known CVEs are common in AI-generated code.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.

Frequently Asked Questions

Is v0 safe to use?

v0 itself is a reputable platform, but apps built with v0 often have security misconfigurations — exposed API keys, missing security headers, and vulnerable dependencies. ScanVibe scans your app to find these issues.

What security issues do v0 apps commonly have?

The most common issues we find in v0 apps are: exposed API keys in frontend JavaScript, missing security headers (CSP, HSTS), outdated dependencies with known vulnerabilities, and misconfigured authentication endpoints.

How do I check if my v0 app is secure?

Enter your app's URL in ScanVibe's scanner. We'll check for exposed secrets, security headers, vulnerable libraries, exposed files, and platform-specific misconfigurations — all in about 30 seconds.

Does ScanVibe scan v0 specifically?

Yes. ScanVibe detects v0 in your stack and runs platform-specific security checks in addition to our standard 8-category analysis.
