Is Lovable Safe?
Last updated: January 12, 2026
An honest security analysis of Lovable for developers considering it for their projects.
Quick Answer
Safe with caution - requires Supabase RLS configurationLovable 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 data across 303 vulnerable API endpoints. Lovable exclusively uses Supabase as its backend, so your app's security depends entirely on proper RLS configuration.
Understanding Lovable Security
When evaluating whether Lovable is safe for your project, it's important to understand the distinction between platform security and application security. Lovable as a platform implements industry-standard security practices for its infrastructure, including encryption, access controls, and regular security audits.
However, the security of applications built with Lovable depends significantly on how developers use the platform. AI-generated code and rapid development workflows can introduce vulnerabilities that exist independently of the platform's underlying security. Research from Stanford University found that AI coding assistants produce vulnerable code approximately 40% of the time when working on security-sensitive tasks.
The most common security issues in Lovable applications stem from misconfigurations, exposed credentials, and missing security controls—problems that developers must address regardless of which platform they use. Understanding these patterns helps you make informed decisions about using Lovable for your specific use case.
Platform Security
Platform security refers to the security measures Lovable implements at the infrastructure level: how they protect their servers, encrypt data in transit and at rest, manage access to their systems, and respond to security incidents. These are controls the platform provider manages on your behalf.
Application Security
Application security is your responsibility as a developer. This includes properly configuring authentication, implementing authorization controls, protecting sensitive data, securing API endpoints, and avoiding common vulnerabilities like exposed credentials or SQL injection. These risks exist regardless of which platform you use.
Common Security Mistakes in Lovable Apps
Based on security scans of thousands of Lovable applications, these are the most frequently encountered vulnerabilities. Understanding these patterns helps you proactively secure your applications.
Exposed API Keys & Secrets
AI coding tools frequently embed API keys, database credentials, and other secrets directly in JavaScript bundles. These credentials become visible to anyone who inspects your application's source code in their browser.
Prevention: Use environment variables and server-side API routes to keep credentials secure.
Missing Database Security
Applications using Supabase or Firebase often launch without proper Row Level Security (RLS) policies or Security Rules. This allows unauthorized users to read, modify, or delete data they shouldn't have access to.
Prevention: Always enable and test RLS policies before deploying to production.
Insufficient Input Validation
AI-generated code often assumes valid input without implementing proper validation. This opens applications to injection attacks, XSS vulnerabilities, and data corruption.
Prevention: Validate all user input on both client and server side.
Missing Security Headers
HTTP security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security are frequently missing from AI-generated applications, leaving them vulnerable to various attacks.
Prevention: Configure security headers in your hosting platform or application middleware.
Known Security Incidents
CVE-2025-48757: Mass RLS Misconfiguration
January 2025Security researchers discovered 303 vulnerable API endpoints across 170+ Lovable apps. Attackers could read user emails, passwords, payment data, and even admin credentials. Some apps had service_role keys exposed, allowing full database takeover.
Security Assessment
Security Strengths
- Built-in 'Security Scan' feature in Lovable dashboard alerts you to RLS issues
- Uses Supabase exclusively - single backend means focused security review
- Deploys to Vercel/Netlify with automatic HTTPS and CDN protection
- Active team that issued guidance after CVE-2025-48757 disclosure
- Generates TypeScript React code with type safety
Security Concerns
- CVE-2025-48757 exposed 303 vulnerable endpoints across 170+ apps
- Lovable AI creates Supabase tables WITHOUT enabling RLS by default
- 83% of exposed Supabase databases involve RLS misconfigurations (Escape.tech)
- Generated code often hardcodes OpenAI/Stripe keys in React components
- No Firebase or other backend options - must learn Supabase security model
Security Checklist for Lovable
- 1Run Lovable's built-in 'Security Scan' from the dashboard
- 2Go to Supabase → Authentication → Policies and enable RLS on EVERY table
- 3Write SELECT/INSERT/UPDATE/DELETE policies that check (select auth.uid()) = user_id
- 4Search codebase for 'sk-' (OpenAI) and 'sk_live' (Stripe) - move to Supabase Edge Functions
- 5Check that service_role key is NOT in any frontend files
- 6Test RLS: run SELECT * FROM your_table; as anonymous in SQL editor - should return 0 rows
The Verdict
Lovable makes building apps incredibly fast, but the January 2025 CVE-2025-48757 incident proved that speed without security review is dangerous. Use Lovable's built-in Security Scan, enable RLS on every Supabase table, and run VAS before launching. The Supabase-only architecture means you only need to master one security model.

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.”
Frequently Asked Questions
Is Lovable safe for production apps?
Lovable can be used for production apps, but requires security review before launch. The CVE-2025-48757 incident showed that default configurations are not production-ready. Use Lovable's built-in Security Scan feature and enable RLS on all Supabase tables.
What was the Lovable security vulnerability (CVE-2025-48757)?
CVE-2025-48757 was a mass RLS misconfiguration discovered in January 2025 that affected 170+ Lovable applications across 303 vulnerable endpoints. Attackers could read and write to Supabase databases, exposing user emails, API keys, payment information, and even admin credentials with service_role key access.
How do I secure my Lovable app?
To secure your Lovable app: 1) Run Lovable's built-in Security Scan from the dashboard, 2) Enable Row Level Security (RLS) on all Supabase tables in the Supabase dashboard, 3) Create policies using (select auth.uid()) = user_id pattern, 4) Move API keys to Supabase Edge Functions, 5) Test by querying as anonymous user.
Does Lovable expose my Supabase API keys?
Lovable apps include the Supabase anon key in frontend code, which is intentional and safe - the anon key is designed to be public. Security comes from Row Level Security (RLS) policies. However, NEVER expose the service_role key, which was found exposed in some CVE-2025-48757 affected apps.
Why does Lovable only use Supabase?
Lovable exclusively uses Supabase as its backend, which simplifies the development experience but means you must understand Supabase's security model. This is different from Bolt.new which supports multiple backends (Supabase, Firebase, etc.). The single-backend approach means focused security review.
