Security & Code Quality

Every code generation runs through an OWASP Top 10 security scanner that detects vulnerabilities and auto-fixes them — not just reports them.

How It Works

GenMB's security scanner runs automatically during every code generation. It analyzes all generated files using static pattern matching — no LLM calls, no external services, no latency impact.

1. Generate

You describe your app and GenMB generates code through the 8-stage pipeline.

2. Scan

The security scanner analyzes all generated files for OWASP Top 10 vulnerabilities in ~50ms.

3. Fix

Critical and high-severity findings are fed into the Code Healer for automatic remediation.

4. Deliver

You receive clean, security-hardened code with a security score.

Non-Blocking

Security scanning never blocks code generation. If the scanner encounters an unexpected error, generation continues normally and delivers your code. Security is additive, not a gate.

What Gets Scanned

The scanner analyzes all generated file types for language-specific vulnerability patterns.

HTML

XSS vectors, insecure inline scripts, dangerous DOM manipulation.

JavaScript / TypeScript

eval(), exposed secrets, insecure fetch, localStorage token storage.

JSX / TSX

dangerouslySetInnerHTML without sanitization, XSS in React components.

Python

SQL injection via f-strings, hardcoded credentials, insecure HTTP calls.

CSS

External resource loading from untrusted origins.

OWASP Top 10 Coverage

Findings are mapped to OWASP Top 10 (2021) categories with actionable fix suggestions.

A02:2021Cryptographic Failures

Hardcoded API keys, tokens, passwords, AWS credentials, private keys.

A03:2021Injection

SQL injection via template literals/f-strings, eval(), new Function(), document.write().

A05:2021Security Misconfiguration

CORS wildcard origin (*), insecure permissions, debug mode in production.

A07:2021Cross-Site Scripting (XSS)

innerHTML assignment, dangerouslySetInnerHTML, insertAdjacentHTML, outerHTML.

A08:2021Insecure Communication

HTTP API calls (non-HTTPS), unencrypted data transmission.

A06:2021Vulnerable Components

Outdated jQuery/Lodash CDN versions with known vulnerabilities.

Auto-Remediation

Unlike competitors that only report security issues, GenMB automatically fixes them. Critical and high-severity findings are converted into healing instructions and fed into the Code Healer.

Hardcoded API keys are moved to environment variables or placeholder patterns.
eval() and new Function() calls are replaced with safe alternatives.
innerHTML assignments are replaced with textContent or sanitized with DOMPurify.
SQL string concatenation is replaced with parameterized queries.
HTTP URLs are upgraded to HTTPS where possible.

Smart Filtering

The scanner intelligently avoids false positives. Environment variables (process.env, import.meta.env), placeholder values, and code with existing sanitization (DOMPurify, sanitize()) are automatically excluded from findings.

Security Score

Every generation produces a security score from 0 to 100, calculated by deducting points based on finding severity.

Critical

-20 points each

High

-10 points each

Medium

-3 points each

Low

-1 point each

After auto-remediation, most generated apps achieve a score of 90-100. The score is included in the generation response metadata.

vs Competitors

GenMB is the only AI app builder that both scans for and automatically fixes security vulnerabilities in generated code.

GenMB

OWASP Top 10 scan + auto-remediation via Code Healer. Runs on every generation, all plans.

Lovable

Security Scan on publish (Supabase-aware). Reports issues but requires manual fixes.

Bolt V2

Teams security scan. Available on Teams plan only. Reports issues.

v0 / Replit

No built-in security scanning.

FAQs

Does the security scanner slow down code generation?▾

No. The scanner uses pure static regex analysis with no LLM calls. It completes in approximately 50 milliseconds and runs in parallel with other validation steps.

What happens if the scanner finds a critical vulnerability?▾

Critical and high-severity findings are automatically fed into the Code Healer, which fixes them before the code is presented to you. You receive clean, remediated code without needing to act on security warnings manually.

Does GenMB scan backend code too?▾

Yes. The scanner analyzes both frontend and backend code. For backend code (FastAPI, Express), it checks for SQL injection via string interpolation, exposed secrets, missing input validation, and other server-side vulnerabilities.

Is this available on the Free plan?▾

Yes. Security scanning runs on every code generation for all plans, including Free. Every user gets the same level of security protection.
