What People Actually Say About Lovable Security
Last updated: June 30, 2026
What developers report on Reddit, X, and forums about Lovable security, checked against what we actually find when we scan Lovable apps.
The Consensus
Great to build with, verify the backendDevelopers love building with Lovable and worry about what it leaves unsecured. The recurring theme is that Lovable provisions a Supabase backend for you, and historically shipped apps with Row Level Security misconfigured. CVE-2025-48757 put real numbers behind the worry. The community view is that Lovable has improved its defaults, but you still cannot assume the database is locked down.
What Keeps Coming Up
The recurring Lovable security themes developers raise, and what our own scans show about each one.
CVE-2025-48757 and leaking apps
The most cited Lovable security event. In May 2025, researcher Matt Palmer documented 170+ Lovable apps leaking data through misconfigured RLS on their Supabase backends. It became the reference point for every 'is Lovable safe' thread.
We still find Lovable-built apps with the same root cause: open Supabase tables and unprotected functions reachable with the public key. The platform improved defaults, but existing and quickly-built apps still slip through.
Exposed keys and secrets in the bundle
Builders report finding API keys in their app's client code and ask whether that is normal. The answer depends on the key, which confuses people.
In our broader scans, exposed secrets in client bundles were common, including, in the worst cases, keys that bypass all database security. Lovable apps inherit this risk because so much logic lives client-side.
How much do I still have to secure myself?
The honest community answer is 'more than you'd hope.' Lovable handles a lot, but authorization rules, rate limiting, and what is exposed in the database are still on you.
Across vibe-coded apps, the issues that only show up under real testing, broken authorization and missing rate limiting, were widespread. Lovable apps are not exempt.

What Developers Praise & Warn About
Commonly Praised
- Fastest path from idea to working app most people have used
- Lovable has tightened security defaults since the 2025 incidents
- Active community and responsive team
- Real apps with real users ship from it every day
Common Complaints
- The provisioned Supabase backend can ship without proper RLS
- AI-generated logic lands client-side, where secrets get exposed
- You still have to understand database security to be safe
- CVE-2025-48757 left a lasting impression on the community
What We Found Scanning Lovable Apps
Lovable apps run on Supabase, so they inherit the single biggest risk we see: a database that works perfectly because its access rules were never turned on.
We continue to find Lovable apps with publicly readable Supabase tables and unprotected RPC functions.
The 2025 CVE-2025-48757 disclosure tied 170+ Lovable apps to the same misconfigured-RLS root cause.
Across vibe-coded apps generally, 96% had a security issue and 62% had a critical or high when deeply tested.
The fixes are almost always configuration, not rewrites: enable RLS, lock down functions, move secrets server-side.
The Bottom Line
Lovable is one of the most loved build tools and one most worth scanning before launch. The community consensus is fair: the app will work, but the Supabase backend it stands up may be wide open, and CVE-2025-48757 showed that at scale. Lovable's defaults are better now, but the only way to know your specific app is locked down is to test the database from an anonymous client. If it is clean, you are in good shape.
Frequently Asked Questions
Is Lovable safe according to the developer community?
The community considers Lovable safe to build with, with one major caveat: verify the Supabase backend it provisions. The widely cited CVE-2025-48757 found 170+ Lovable apps leaking data through misconfigured Row Level Security. Lovable has since improved defaults, but you should still confirm your own app's database is locked down.
What was the Lovable CVE-2025-48757 issue?
In May 2025, security researcher Matt Palmer documented that 170+ apps built with Lovable were exposing data because Row Level Security on their Supabase backends was misconfigured. It became the defining reference point for Lovable security discussions.
Do I still need to secure a Lovable app myself?
Yes. Lovable handles a lot, but Row Level Security, authorization rules, rate limiting, and keeping secrets out of the client bundle still need verification. These are exactly the issues our scans find most often in vibe-coded apps.
