Is Lovable safe?
Lovable ships fast; its default app template is light on security. Here is what actually breaks in production Lovable apps and how to harden one in 30 minutes.
Lovable apps ship with reasonable auth scaffolding but routinely misconfigure Supabase RLS, expose secrets via the Vite bundle, and lack rate limits on API endpoints. Assume your default Lovable app is not safe to ship to real users until you run a scan.
How it fails in production
Supabase RLS misconfiguration
The most common failure mode. Lovable's Supabase integration generates migrations, but RLS policies are inconsistent and often default-allow or scope by user only (not tenant). Vibe Leak Index shows ~16% of Lovable apps have at least one RLS-disabled table.
VITE_ / PUBLIC_ env vars leaked client-side
Any environment variable with the wrong prefix ships in the JS bundle. Lovable's code generator sometimes picks the wrong prefix when wiring third-party services.
Project-enumeration vulnerability (CVE-2025-48757)
Disclosed in 2025; per Cyber Kendra's April 2026 report, re-broken. Run the /tools scanner to verify your specific project.
No rate limits on AI-feature endpoints
Lovable apps that integrate OpenAI / Claude / Gemini routinely ship without rate limits. One leaked key + no cap = $50K bill overnight.
How to ship safely on Lovable
- Enable RLS on every Supabase table and add default-deny policies
- Audit env vars: VITE_/PUBLIC_ only for public constants, never keys
- Install Securie on the GitHub repo Lovable writes to
- Add rate limits on every paid-API route
- Verify your project against the Lovable exposure checker
Securie's specialists cover every failure mode above — Supabase RLS analyzer, client-bundle secret scanner, rate-limit detector on paid-API call sites, and Lovable-specific checks.
Verdict
Lovable is safe if you treat its output as AI-generated code that needs review. It is not safe if you assume the platform's defaults will protect you.
