Bolt.new + Firebase Security

Bolt.new can quickly integrate Firebase for auth and database. But Firebase's security depends entirely on properly written Security Rules - which AI often skips.

Why Bolt + Firebase?

Firebase is a popular alternative to Supabase in Bolt.new projects, especially for real-time features. The Firebase integration is quick but Security Rules require manual configuration.

Common Vulnerabilities

These are the security issues we find most often in Bolt apps using Firebase.

critical

Test Mode Security Rules

Firebase projects often launch with permissive test rules that allow anyone to read/write all data.

high

Missing Rule Validation

Security Rules may check authentication but not validate data structure or ownership.

critical

Admin SDK in Frontend

AI may accidentally include Firebase Admin SDK credentials in client-side code.

high

Overly Broad Collection Access

Rules may grant access to entire collections when only specific documents should be accessible.

What We Check for Bolt + Firebase

Security Rules Analysis

Test Firestore and Realtime Database rules for proper access control.

Admin Credential Detection

Scan for service account keys in frontend bundles.

Rule Coverage

Verify all collections have appropriate Security Rules.

Data Validation

Check if rules validate data structure and ownership.

Quick Security Wins

Apply these fixes right now to improve your security.

Replace test rules with production rules requiring auth
Add request.auth != null to all read/write rules
Validate data ownership with request.auth.uid == resource.data.userId
Remove any Admin SDK code from frontend
Use Firebase Emulator to test rules before deploying

The Bottom Line

Bolt.new + Firebase needs Security Rules written before launch. Test mode rules are a common vulnerability - never deploy with them.

Find Security Rules misconfigurations, exposed credentials, and other vulnerabilities before attackers do.
