Can Bolt.new apps be hacked?

Bolt.new-Specific Attack Vectors

These are the paths attackers actually take into Bolt.new applications — not a generic OWASP list, but what automated scanners and security researchers find when they look at Bolt.new apps specifically, given the stack (Supabase (Postgres + RLS) as the database):

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.

**Supabase-Specific Risk**: Bolt.new apps typically ship with the public Supabase anon key embedded in frontend code. That is by design — but only works safely if Row Level Security is enabled on every table. Attackers routinely query Supabase endpoints directly using the anon key from your bundle. A single table without RLS is a full data leak.

Real-world example

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

How attackers find these issues

Attackers don't target Bolt.new apps specifically — they run automated scanners across the entire internet looking for known patterns. Supabase URLs follow a predictable pattern (`*.supabase.co`), making Bolt.new apps easy to fingerprint. Once identified, the scanner probes the specific vulnerability classes listed above.

What a security scan of a Bolt.new app looks at

• **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.
