Question 1

Can Lovable apps be hacked?

Accepted Answer

Yes, AI-generated code from Lovable often contains security vulnerabilities that attackers can exploit. Common issues include missing Row Level Security (RLS) on Supabase tables, exposed API keys in client-side code, and lack of input validation. Since Lovable generates full-stack applications rapidly, security best practices are frequently omitted in favor of functionality. UNPWNED scans Lovable apps for these exact vulnerabilities, checking for exposed secrets, missing RLS policies, and insecure configurations.

Question 2

Is Lovable safe for production?

Accepted Answer

Lovable can produce production-ready applications, but the generated code requires thorough security review before deployment. The AI focuses on delivering working features quickly, which means security measures like authentication guards, rate limiting, and proper error handling may be incomplete. Many developers ship Lovable apps without reviewing the generated Supabase policies or API route protections. Run an UNPWNED scan before going live to identify and fix security gaps in your Lovable application.

Question 3

Does Lovable expose API keys?

Accepted Answer

CVE-2025-48757 documented a critical vulnerability where Lovable-generated projects exposed Supabase service_role keys in client-side code. The service_role key bypasses all Row Level Security policies, giving anyone with the key full read and write access to the entire database. While Lovable has taken steps to address this, older projects and certain configurations may still be affected. UNPWNED specifically checks for exposed Supabase keys, Firebase credentials, and other secrets in your application code.

Question 4

How to secure a Lovable app?

Accepted Answer

Start by enabling Row Level Security on every Supabase table and writing proper RLS policies that restrict data access per user. Rotate any API keys that may have been exposed in client-side code, especially the Supabase service_role key. Add security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to your deployment configuration. Implement rate limiting on API endpoints and validate all user input on the server side. UNPWNED provides a comprehensive security scan that covers all of these checks for Lovable applications.

Question 5

Does Lovable add security headers?

Accepted Answer

No, Lovable does not automatically add security headers to generated applications. Critical headers like Content-Security-Policy (CSP), X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security are typically missing from Lovable projects. Without these headers, your application is more vulnerable to cross-site scripting (XSS), clickjacking, and MIME-type sniffing attacks. You need to manually configure these headers in your deployment platform or middleware. UNPWNED checks for all recommended security headers and reports which ones are missing.

Question 6

Are Lovable Supabase tables secure by default?

Accepted Answer

No, Lovable-generated Supabase tables frequently lack proper Row Level Security (RLS) policies. When RLS is disabled or misconfigured, any authenticated user can read, modify, or delete data belonging to other users. Lovable may create tables with RLS enabled but without restrictive policies, which effectively leaves them open. This is one of the most common and dangerous vulnerabilities in Lovable applications. UNPWNED scans your Supabase configuration to detect tables with missing or overly permissive RLS policies.

Question 7

Can Lovable apps leak user data?

Accepted Answer

Yes, without proper Row Level Security policies, any authenticated user can potentially access all data in your Supabase database. This means user profiles, emails, payment information, and any other stored data could be exposed through simple API calls. The risk increases when the anon or service_role key is exposed in client-side code, as it enables unauthenticated access to unprotected tables. Data leaks from misconfigured Lovable apps have been publicly documented by security researchers. UNPWNED tests for data exposure risks by checking RLS policies, key exposure, and API endpoint security.

Question 8

How to check if my Lovable app is vulnerable?

Accepted Answer

The fastest way to assess your Lovable app security is to run an automated security scan that checks for the most common AI-generated code vulnerabilities. Key areas to verify include whether your Supabase service_role key is exposed in client-side JavaScript, whether RLS is enabled and properly configured on all tables, and whether security headers are present. You should also check for open API routes that lack authentication and input validation. UNPWNED runs 700+ security checks across 40 scanners specifically relevant to Lovable and other AI-built applications.

Question 9

Does Lovable support rate limiting?

Accepted Answer

No, Lovable does not include built-in rate limiting for generated API endpoints. Without rate limiting, your application is vulnerable to brute-force attacks, credential stuffing, and denial-of-service attempts. Attackers can also abuse unprotected endpoints to scrape data or exhaust your Supabase quotas. You need to implement rate limiting manually using middleware, edge functions, or a service like Cloudflare. UNPWNED checks whether your API endpoints have rate limiting protection in place.

Question 10

What security testing should I do before launching a Lovable app?

Accepted Answer

Before launching, scan for exposed API keys and secrets in your client-side bundle, verify that Row Level Security is enabled with proper policies on every Supabase table, and confirm that security headers are configured on your deployment. Check that all API routes require authentication where appropriate and that user input is validated server-side. Test that your application handles errors gracefully without leaking stack traces or internal information. UNPWNED performs all of these checks in a single automated scan, giving you a security score and actionable fix recommendations for your Lovable app.
