Is Your Lovable App Safe to Launch?
Security checklist for Lovable apps before going live. 89% of Lovable apps are missing Supabase RLS. Covers the VibeScamming vulnerability, exposed secrets, unauthenticated routes, and what to fix before your first real user.
Lovable makes it fast to build an app with a real database, real auth, and a working frontend. But "working" in Lovable's environment and "safe for real users" are two different things. A May 2025 audit of 1,645 Lovable-generated apps found a 10.3% data-exposure vulnerability rate — 170 apps with real user data at risk.
If you're planning to launch, or you've already launched, this checklist covers the five security issues that appear most frequently in Lovable apps — and what to do about each one.
The VibeScamming vulnerability (April 2025)
A documented class of security vulnerabilities in Lovable apps was named "VibeScamming" after researchers showed that Lovable could be prompted to generate apps with intentional authorization gaps — apps that appeared functional but silently exposed user data. The vulnerability demonstrated that AI-generated code should never be assumed to be secure without independent review.
The 5-Point Security Checklist
01. Supabase Row-Level Security (RLS) enabled on all tables
critical“Can any authenticated user read every row in your database?”
This is the most widespread security gap in Lovable apps. Lovable uses Supabase as its database layer, and Supabase ships with RLS disabled by default. If Lovable creates a table without enabling RLS, any authenticated user can query the entire table — every user's data, every record, no restrictions. The May 2025 audit found 89% of Lovable apps were missing this.
How to check this:
- •Open your Supabase project and go to the Table Editor
- •For each table, check whether RLS is enabled (it should show a lock icon when enabled)
- •If RLS is disabled on any table that stores user data, stop here and fix it before launch
- •Review existing RLS policies — enabled is not enough if the policy allows unrestricted reads
02. No exposed API keys in the frontend bundle
critical“Are any Supabase service keys, OpenAI keys, or Stripe keys in your client-side code?”
Lovable runs your app logic in the browser by default. If an API key gets included in a client-side component — even wrapped in an environment variable like NEXT_PUBLIC_ — it is visible to anyone who opens browser dev tools. The Supabase anon key is meant to be public. The service_role key is never meant to be in the frontend. The distinction matters enormously.
How to check this:
- •Search your Lovable codebase for service_role — it should never appear in frontend code
- •Verify that your Supabase anon key is the only database credential accessible client-side
- •Any Stripe, OpenAI, or third-party API keys should be in server-side functions only, never in browser-accessible code
- •Check your Supabase environment variables tab to confirm which keys are set
03. Server-side authentication checks on all data operations
critical“Does your app verify the user's identity on the server before returning or modifying data?”
Lovable's frontend can enforce UI-level access controls — e.g. only showing certain buttons to logged-in users. But UI guards are trivially bypassed. Any operation that reads or writes sensitive data needs to check authentication on the server side, not just in the component that triggered it.
How to check this:
- •Review every Supabase query in your app — does each one use auth.uid() to scope the result to the current user?
- •If you have any edge functions or server actions, verify they check for a valid session before executing
- •Test by attempting to access data endpoints with a tool like Postman without a valid auth token
04. Input validation and sanitization
high“What does your app do with unexpected or malicious input?”
Lovable generates forms that handle the expected happy-path input. It does not add comprehensive validation — so empty strings, oversized payloads, script tags, or malformed data may be accepted and stored without error. This can lead to stored XSS vulnerabilities, broken queries, or corrupted data.
How to check this:
- •Test every form with empty fields, very long strings (1,000+ characters), and special characters like < > & " '
- •Verify that required fields are enforced both in the UI and on the server side
- •Check that your Supabase tables have appropriate NOT NULL, length, and type constraints
05. GitHub repository does not contain secrets
high“Has any sensitive credential ever been committed to your git history?”
When Lovable syncs to GitHub, it exports your code as-is. If any credential was ever inline in your code during a GitHub sync — even if you removed it later — it may be in your git history. Git history is often public or accessible to anyone with repo access.
How to check this:
- •Run a search in your git history for common secret patterns: sk-, pk-live, service_role, DATABASE_URL
- •Use a tool like git-secrets or TruffleHog to scan the full commit history
- •If any secret is found in history, rotate that credential immediately — removing it from history is complex and the credential should be considered compromised
Which Issues Can Be Fixed in Lovable?
| Issue | Fix in Lovable / Supabase? | Requires code ownership? |
|---|---|---|
| Missing RLS | Yes — enable in Supabase dashboard and write policies | No, but policies need to be correct |
| Exposed API keys | Yes — move to Supabase environment settings | Yes, for any that were already committed |
| Unauthenticated server calls | Partially — Supabase policies help; server functions need review | Yes, for complete control |
| Input validation | Partially — Supabase constraints help; frontend validation via Lovable | Yes, for server-side validation |
| Git history secrets | No — requires rotating credentials and cleaning git history | Yes |
