Can Lovable apps be hacked?

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.

Lovable-Specific Attack Vectors

These are the paths attackers actually take into Lovable applications — not a generic OWASP list, but what automated scanners and security researchers find when they look at Lovable apps specifically, given the stack (Supabase (Postgres + RLS) as the database):

1. **Complete Database Exposure via Missing RLS**: Supabase tables without Row Level Security can be queried by anyone with the public anon key.

2. **API Key Theft from JS Bundles**: OpenAI, Stripe, and other API keys hardcoded in frontend code are easily extracted.

3. **Account Takeover via Weak Auth**: Missing email verification and weak passwords enable account compromise.

4. **Data Manipulation via Open RLS**: Even if RLS exists, overly permissive policies allow cross-user data modification.

5. **XSS via Missing Security Headers**: Without CSP and other headers, injected scripts can steal sessions and data.

**Supabase-Specific Risk**: Lovable apps typically ship with the public Supabase anon key embedded in frontend code. That is by design — but only works safely if Row Level Security is enabled on every table. Attackers routinely query Supabase endpoints directly using the anon key from your bundle. A single table without RLS is a full data leak.

Real-world example

CVE-2025-48757: 170+ Lovable apps had exposed databases discovered and reported.

How these issues get discovered

This isn't targeted — automated scanners run across the entire internet looking for known patterns, and Lovable apps surface like everything else. Supabase URLs follow a predictable pattern (`*.supabase.co`), making Lovable apps easy to fingerprint. Once identified, the scanner probes the specific vulnerability classes listed above.

What a security scan of a Lovable app looks at

• **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.
