Top 5 Security Issues in Bolt.new Apps

1

Exposed API Keys

OpenAI, Stripe, and other secret keys hardcoded directly in frontend JavaScript bundles. Attackers can extract these keys and use your API quotas, make purchases, or access your services.

2

Missing Supabase RLS

Database tables accessible to anyone with the anon key because Row Level Security policies haven't been configured. This means any user can read, modify, or delete all data in exposed tables.

3

No Security Headers

Missing Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options headers leave your app vulnerable to cross-site scripting, man-in-the-middle attacks, and clickjacking.

4

Weak Authentication

No minimum password requirements, missing email verification, and lack of rate limiting on login endpoints allows brute force attacks and account takeovers.

5

Source Map Exposure

Production source maps uploaded to hosting reveal your entire application source code, including business logic, API endpoints, and potentially sensitive comments.

Where Security Breaks in Bolt.new Apps

Built on Supabase (Postgres + RLS), Bolt.new applications share a recognizable fingerprint, which means attackers and automated scanners find them the same way every time. Based on real vulnerability patterns in Bolt.new deployments, the breakdown is 2 critical-impact issues, 2 high-impact, and 1 medium-or-lower.

Real-world observation

Common to find OpenAI keys, database passwords, and OAuth secrets in Bolt projects.

CRITICAL

Hardcoded Secrets in Generated Code

Bolt generates working demos with API keys directly in source files.

Fix: Audit all generated code. Move secrets to environment variables before deployment.

CRITICAL

Database Without Security Rules

Firebase or Supabase databases created without any access controls.

Fix: Configure Security Rules (Firebase) or RLS (Supabase) before going live.

MEDIUM

Source Code Exposure via Source Maps

Production builds include source maps revealing original code structure.

Fix: Disable source maps in production: productionBrowserSourceMaps: false

HIGH

Client-Side Auth Bypass

Auth checks only in frontend code can be bypassed by calling APIs directly.

Fix: Always verify authentication server-side. Never trust client-side auth state.

HIGH

Injection via Unvalidated Input

AI-generated code often trusts user input without validation.

Fix: Add input validation on all endpoints. Use parameterized queries.

What We Check

Secret Detection

Scans all JavaScript bundles for API keys, tokens, and credentials that should never be in frontend code. We detect OpenAI keys, Stripe secrets, AWS credentials, database connection strings, and dozens of other sensitive patterns.

Database Security

Tests Supabase/Firebase for proper security rules. We query your tables to verify they're protected.

Security Headers

Checks for all important HTTP security headers that prevent XSS, clickjacking, and MITM attacks.

Auth & Sessions

Analyzes authentication implementation for weak passwords, session issues, and rate limiting gaps.

Why Bolt.new Apps Need Security Scanning

Bolt.new enables you to build full-stack applications in minutes using AI-powered code generation. While this dramatically accelerates development, the generated code often prioritizes functionality over security. Features that would take days to build manually are created in seconds, but security configurations require careful attention that AI assistants can overlook.

Most Bolt.new applications connect to Supabase for database and authentication. Supabase is secure by default, but requires explicit Row Level Security (RLS) policies to protect your data. Without these policies, your database tables are accessible to anyone who can view your frontend code and extract the Supabase anon key.

vas was built specifically to catch the security issues common in AI-generated applications. We test your actual deployed application, checking for exposed API keys, verifying database security policies, analyzing authentication strength, and ensuring proper security headers are configured on your hosting platform.

How Bolt.new Security Scanning Works

1

Submit Your URL

Enter your Bolt application URL. Our scanner automatically detects your tech stack and configures the appropriate security checks for Bolt.new.

2

Automated Analysis

We check the reachable app for exposed secrets, browser protections, authentication issues and database access problems. A standard scan typically takes a few minutes; blocked requests or incomplete coverage are reported.

3

Get Actionable Results

Receive a detailed report with prioritized vulnerabilities, severity ratings, and step-by-step remediation guidance with code examples specific to Bolt.new.

Common Questions About Bolt.new Security

What does a VAS scan of a Bolt.new app check?

VAS checks the deployed pages, scripts and endpoints it can reach for issues including secret detection, database security, security headers, auth & sessions. The report records findings and coverage limits; it does not certify the whole app as secure.

What will I receive in the report?

Findings include severity, supporting evidence and remediation guidance. Your first scan is free, with issue counts and one finding revealed in detail. Paid report access unlocks every finding. Use Export for AI to bring available findings into your coding tool, review the proposed changes and retest.

Can a scan verify every permission and private workflow?

No. Coverage depends on reachable pages, discovered endpoints and enabled checks. Configure a test login for supported authenticated checks. Review source code and business-specific permissions separately. Zero findings does not prove an app is secure.

Does VAS change my code or database policies?

VAS provides recommendations, not automatic fixes. Adapt any suggested policy or code change to your data model, test that permitted users still have access and that other users do not, then rescan. Read checks alone cannot confirm insert, update or delete permissions.

What should I know before scanning a production app?

Only scan apps you own or have permission to test. Scan requests can trigger firewall rules, logs and rate limits. Review enabled checks, and use staging or dedicated test accounts for sensitive workflows. Active tests, where enabled, need separate care because they can make changes.

Remediation Playbook for Bolt.new

Priority-ordered fixes for the specific findings we see in Bolt.new apps. Critical items close data-exposure gaps; high items prevent compromise; medium items reduce attack surface. Applies to apps using Supabase (Postgres + RLS), the dominant Bolt.new stack.

1. Hardcoded Secrets in Generated Code

Why it matters: Bolt generates working demos with API keys directly in source files.

How to close it: Audit all generated code. Move secrets to environment variables before deployment.

2. Database Without Security Rules

Why it matters: Firebase or Supabase databases created without any access controls.

How to close it: Configure Security Rules (Firebase) or RLS (Supabase) before going live.

3. Source Code Exposure via Source Maps

5. Injection via Unvalidated Input

Why it matters: AI-generated code often trusts user input without validation.

How to close it: Add input validation on all endpoints. Use parameterized queries.

Verify the fixes stuck

Rescan after deploying a fix to check whether the original finding still appears. Compare the evidence and coverage with the previous report. For permissions and private workflows, also repeat the relevant tests with authorized and unauthorized test users.
