Security Analysis

Is Lovable Safe?

An honest security analysis of Lovable for developers considering it for their projects.

Quick Answer

Safe with caution - requires security review

Lovable is generally safe to use, but apps built with it require security review. A critical RLS vulnerability (CVE-2025-48757) affected 170+ apps in January 2025, exposing user data. Your app's security depends on proper Supabase configuration.

Known Security Incidents

CVE-2025-48757: Mass RLS Misconfiguration

January 2025

Security researchers discovered that 170+ Lovable apps had misconfigured Supabase RLS, exposing sensitive user data including emails, API keys, and payment information.

Security Assessment

Security Strengths

  • Uses Supabase which has strong built-in security when configured correctly
  • Deploys to Vercel/Netlify which have good security defaults
  • Active development team that responds to security issues
  • AI generates modern React code with reasonable practices

Security Concerns

  • AI often skips Row Level Security (RLS) configuration
  • API keys may be exposed in frontend code
  • CVE-2025-48757 showed widespread RLS misconfigurations
  • Security headers often not configured
  • Authentication may have weak password requirements

Security Checklist for Lovable

  • 1
    Enable Row Level Security (RLS) on ALL Supabase tables
  • 2
    Verify RLS policies restrict access to user's own data
  • 3
    Check that no API keys are exposed in frontend JavaScript
  • 4
    Ensure authentication has strong password requirements
  • 5
    Verify security headers are configured in hosting
  • 6
    Run a security scan before going to production

The Verdict

Lovable is a powerful tool for rapid app development, but you must verify security before launching. The January 2025 incident showed that default configurations are not production-ready. Always scan your app and configure Supabase RLS properly.

What Security Experts Say

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.
