Short Answer

Lovable apps surface a predictable distribution of issues: 2 critical-impact classes (complete database exposure via missing rls, data manipulation via open rls), 3 high-impact, 0 medium-or-below. The critical ones are what cause data breaches.

Detailed Answer

Headline incident: CVE-2025-48757: Lovable RLS Vulnerability

In January 2025, a critical RLS misconfiguration was discovered affecting 170+ Lovable apps, exposing emails, API keys, payment details, and personal data. This vulnerability highlights why scanning your Lovable app for security issues is essential before launch.

Critical issues in Lovable apps

  • **Complete Database Exposure via Missing RLS**: Supabase tables without Row Level Security can be queried by anyone with the public anon key. *(Observed: CVE-2025-48757: 170+ Lovable apps had exposed databases discovered and reported.)*
  • **Data Manipulation via Open RLS**: Even if RLS exists, overly permissive policies allow cross-user data modification.

High-severity issues

  • **API Key Theft from JS Bundles**: OpenAI, Stripe, and other API keys hardcoded in frontend code are easily extracted.
  • **Account Takeover via Weak Auth**: Missing email verification and weak passwords enable account compromise.
  • **XSS via Missing Security Headers**: Without CSP and other headers, injected scripts can steal sessions and data.

Why these are the issues specific to Lovable

Lovable apps ship with a recognizable stack (supabase). The issue list above is what appears when you scan that specific combination. A Firebase-backed app would have a different top-5; a self-hosted Postgres deployment would have yet another. Context is everything.

What VAS checks in a Lovable scan

  • **Supabase Security** — Most Lovable apps use Supabase. We test your RLS policies by actively querying tables to verify they're protected.
  • **API Key Exposure** — Scans your JavaScript bundles for exposed API keys from OpenAI, Stripe, and other services that should be server-side.
  • **Authentication Security** — Checks your auth configuration for weak passwords, missing email verification, and rate limiting issues.
  • **Security Headers** — Verifies you have proper HTTP security headers to prevent XSS, clickjacking, and other client-side attacks.

Expert Perspectives

There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.

It's not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.

More Questions About This Topic

Which Lovable security issue is most dangerous?

Complete Database Exposure via Missing RLS. Supabase tables without Row Level Security can be queried by anyone with the public anon key. Real-world evidence: CVE-2025-48757: 170+ Lovable apps had exposed databases discovered and reported. The fix: Enable RLS on all tables and write policies that verify auth.uid() matches data ownership.

Are these issues unique to Lovable, or do they appear across platforms?

The patterns overlap with bolt, v0, replit — all vibe-coding platforms share the "AI-generated code prioritizes functionality over security" problem. But the *specific manifestation* differs per platform. An exposed Supabase anon key is structurally different from an exposed Firebase config, which is different from an exposed Postgres connection string. The right scan is platform-aware.

How do I see which of these issues my Lovable app has?

Run a VAS scan against your deployed Lovable app URL. It checks every issue in the list above, confirms each by actually probing (not just reading headers), and prioritizes by severity with copy-paste fixes. Most Lovable app scans return results in 2–3 minutes.
