Common Firebase Vulnerabilities We Detect

AI Agents Built for Firebase

Our agents are trained on Firebase architecture and equipped with specialized tooling for Firestore, RTDB, and Cloud Storage security testing. They understand the nuances of Firebase security that most pentesters miss.

Firestore Rules Bypass

high

Missing or weak Firestore security rules allow unauthorized access to documents. Attackers can read, modify, or delete data belonging to other users.

// Vulnerable: Open read/write access rules_version = '2'; service cloud.firestore { match /databases/{database}/documents { match /{document=**} { allow read, write: if true; } } }
// Fixed: User-scoped access rules_version = '2'; service cloud.firestore { match /databases/{database}/documents { match /users/{userId} { allow read, write: if request.auth != null && request.auth.uid == userId; } } }

API Key Exposure

high

Firebase API keys exposed without proper restrictions can be abused for quota theft, data access, or service impersonation. Keys need domain and API restrictions.

// Exposed in client code without restrictions const firebaseConfig = { apiKey: "AIzaSyB...", // Unrestricted! authDomain: "app.firebaseapp.com", projectId: "my-app" };
// Safe: API key with restrictions in GCP Console // 1. Application restrictions: HTTP referrers // 2. API restrictions: Only required APIs // 3. Firebase App Check enabled

RTDB Permission Issues

high

Realtime Database with overly permissive rules exposes your entire database tree. Attackers can enumerate and exfiltrate all data.

// Vulnerable: World-readable database { "rules": { ".read": true, ".write": true } }
// Fixed: Authenticated user access only { "rules": { "users": { "$uid": { ".read": "$uid === auth.uid", ".write": "$uid === auth.uid" } } } }

Cloud Storage Rules

medium

Misconfigured Cloud Storage rules can expose private files to public access or allow unauthorized uploads that could be used for malware distribution.

// Vulnerable: Public read/write rules_version = '2'; service firebase.storage { match /b/{bucket}/o { match /{allPaths=**} { allow read, write: if true; } } }
// Fixed: User-scoped storage access rules_version = '2'; service firebase.storage { match /b/{bucket}/o { match /users/{userId}/{allPaths=**} { allow read, write: if request.auth != null && request.auth.uid == userId; } } }
