vibesec 0.2.0

Security scanner for AI-generated code

🔒 VibeSec

Security scanner for AI-generated code.

45% of AI-generated code ships with critical vulnerabilities. Cursor, Claude Code, Bolt, and Lovable generate insecure patterns that existing tools miss. VibeSec catches them before you deploy.

$ vibesec scan ./my-cursor-app

  CRITICAL — Hardcoded Secret
  File: src/lib/supabase.ts  Line: 12
  Found: SUPABASE_SERVICE_KEY hardcoded in source code
  Fix:   Move to environment variables. Never commit secrets to git.

Why VibeSec

Existing tools like Semgrep, Snyk, and CodeQL are great — but they were built for human-written code. AI tools generate specific anti-patterns that these scanners miss:

Pattern	Semgrep	Snyk	VibeSec
Hardcoded secrets	✓	✓	✓
Supabase RLS disabled	✗	✗	✓
Hallucinated npm packages	✗	✗	✓
Missing auth on scaffolded routes	Partial	✗	✓
Source map exposure in build config	✗	✗	✓
AI-specific JWT misuse	✗	✗	✓

Install

pip install vibesec

Usage

Scan a directory:

vibesec scan ./my-project

Scan and get AI-powered fix suggestions:

vibesec scan ./my-project --fix

Export results as JSON (for CI/CD):

vibesec scan ./my-project --output json

Filter by severity:

vibesec scan ./my-project --severity critical

Ignore specific checks:

vibesec scan ./my-project --ignore rls,cors

What VibeSec Checks

🔴 CRITICAL

1. Hardcoded Secrets API keys, passwords, tokens, and database URLs hardcoded in source files. LLMs replicate tutorial patterns where secrets are hardcoded.

# VibeSec catches this
api_key = "sk-abc123..."
SUPABASE_SERVICE_KEY = "eyJhbGci..."
stripe_secret = "sk_live_..."

2. Supabase RLS Disabled Row Level Security disabled — any authenticated user can read or modify all data. LLMs skip RLS to make queries work quickly in scaffolding.

-- VibeSec catches this
ALTER TABLE users DISABLE ROW LEVEL SECURITY;

🟡 HIGH

3. Missing Route Authentication Admin and sensitive API routes scaffolded without authentication middleware. LLMs build the happy path without thinking about access control.

4. Hallucinated Packages npm packages that don't exist — a typosquatting attack surface. LLMs generate plausible-sounding package names that aren't real.

// VibeSec catches this
"react-auth-handler": "^1.0.0",
"supabase-helpers": "^2.1.0"

5. Source Map Exposure Build config exposes full source code via .map files in production.

🟠 MEDIUM

6. Unsafe JWT Handling — JWT decoded without verification, or none algorithm accepted

7. dangerouslySetInnerHTML — Direct HTML injection without sanitization

8. Client-Side Role Trust — Admin checks done using localStorage values

9. Missing Webhook Verification — Stripe/GitHub webhooks without signature check

10. Permissive CORS — Wildcard CORS with credentials enabled

Contributing

VibeSec is open source and contributions are welcome.

Adding a new rule:

1. Create vibesec/rules/your_rule.py
2. Implement check_your_rule(file_path, content) -> list[dict]
3. Register it in vibesec/rules/__init__.py
4. Add test cases in tests/corpus/
5. Open a PR

Each finding must return:

{
    "rule": "Rule Name",
    "severity": "CRITICAL|HIGH|MEDIUM|LOW",
    "file": file_path,
    "line": line_number,
    "message": "What was found",
    "fix_hint": "How to fix it",
    "code_snippet": "offending line"
}

See CONTRIBUTING.md for full guide.
