Is Lovable's built-in security scan enough? What Quick Scan and Deep Scan check — and what they don't
Short answer
Lovable’s Quick Scan runs automatically at publish and checks database access rules and RLS gaps, password-protection settings, known vulnerabilities in npm dependencies and unauthenticated MCP servers. Deep Scan is on-demand and adds authorization, abusable endpoints, injection, leaked secrets, payment manipulation, auth bypass and data exposure in logs. Lovable itself states the scans cannot guarantee security, do not replace a professional review for apps handling sensitive data, and do not cover runtime behavior, business-logic flaws or compliance beyond OWASP patterns. Use the scans, then test the deployed app.

- Quick Scan runs automatically on publish and when dependency files change.
- Deep Scan runs on demand (automatically at publish for MCP-integrated apps); scheduled Deep Scans are Enterprise-only.
- Lovable’s docs: the tools “cannot guarantee complete security” and “do not replace a thorough security review” for sensitive-data apps.
- Not covered per Lovable: production runtime issues not visible in code, business-logic flaws, compliance beyond OWASP patterns.
What Quick Scan checks
- Database access rules, Row Level Security gaps and password-protection settings.
- Known vulnerabilities in npm dependencies.
- Unauthenticated MCP servers.
What Deep Scan adds
- Access control and authorization violations (users reaching other users’ data).
- Unauthenticated or abusable endpoints.
- Unsafe input and injection — into queries, commands, file paths, browsers, emails and AI prompts.
- Leaked secrets and credentials hardcoded in source.
- Payment and billing manipulation.
- Authentication bypass.
- Personal and sensitive data exposed in error messages and logs.
The gaps, in Lovable’s own words
Lovable’s documentation is explicit that Deep Scan findings are theoretical until confirmed by dynamic testing, and that the scans do not cover runtime vulnerabilities, business logic or compliance. For apps that handle sensitive data it recommends an additional professional review.
In practice that leaves four things you have to check on the deployed app:
- What the live site actually returns. Security headers (CSP, HSTS, frame protection), cookies and CORS are set by hosting, not by your code.
- What is in the shipped bundle. Environment variables prefixed for the client (
VITE_,NEXT_PUBLIC_) are inlined into JavaScript anyone can download. - Whether RLS holds against real requests. A policy can exist and still be
using (true). - Edge Functions and webhooks that are callable without a valid user or signature.
What external scans see that a code scan does not
In Sekrd’s dataset of 799 hosts scanned between March and September 2026 (174 of them on lovable.app subdomains), the most common issues across all hosts were deployment-level, not code-level: 81.5% served no Content-Security-Policy, 93.4% disclosed server software versions, and 60.3% had no privacy-policy link. None of these appear in a source-code scan.
A practical workflow
- Fix every Quick Scan finding before publishing.
- Run Deep Scan before any release that touches auth, payments or user data.
- Scan the deployed URL from outside, signed out, as an attacker would.
- Re-scan after every publish — the app on the internet is the one that matters.
Frequently asked questions
Does Lovable scan my app for security issues automatically?
Yes. Quick Scan runs automatically when you publish and when dependency files change. It checks database access rules and RLS gaps, password protection, npm dependency vulnerabilities and unauthenticated MCP servers. Deep Scan is on-demand.
Is Lovable’s security scan enough before launch?
Lovable’s own documentation says the scans cannot guarantee complete security and do not replace a professional review for apps handling sensitive data. They do not cover runtime behavior, business logic or compliance beyond OWASP patterns, so the deployed app should also be tested from outside.
What does Lovable Deep Scan check?
Authorization violations, unauthenticated or abusable endpoints, injection (including into AI prompts), hardcoded secrets, payment manipulation, authentication bypass and sensitive data exposed in errors and logs.
