What security issues do Firebase apps have?
Get instant answers about your app's security.
Short Answer
Common Firebase security issues include exposed databases, hardcoded API keys, missing security headers, and weak authentication.
Detailed Answer
Based on our scans, the most common Firebase security issues are:
**Critical Issues:** - Database tables without access controls (open to anyone) - API keys hardcoded in JavaScript bundles - Service/admin keys exposed in frontend code
**High Severity Issues:** - Missing or weak RLS/Security Rules - No rate limiting on authentication - Source maps exposing source code
**Medium Severity Issues:** - Missing security headers (CSP, HSTS, X-Frame-Options) - Weak password requirements - Session cookies without secure flags
VAS checks for all these issues and provides remediation guidance for each finding.

Expert Perspectives
“Vibe coding your way to a production codebase is clearly risky. Most of the work we do as software engineers involves evolving existing systems, where the quality and understandability of the underlying code is crucial.”
“The problem with AI-generated code isn't that it doesn't work - it's that it works just well enough to ship, but contains subtle security flaws that are hard to spot.”

Which Firebase security issue is most dangerous?
Database exposure without access controls is the most critical - it allows anyone to read, modify, or delete all your data. This is caused by missing RLS (Supabase) or permissive Security Rules (Firebase). Fix this before any other issue.
Are these issues unique to Firebase?
No, these security issues are common across all vibe coding tools - Lovable, Bolt, Replit, etc. They stem from AI-generated code prioritizing functionality over security. The issues are the same regardless of which tool you use.
How do I know which issues my Firebase app has?
Run a VAS security scan. We automatically check for all common vulnerabilities and prioritize findings by severity. You'll get a report showing exactly which issues exist and how to fix each one.
