Lovable app security checklist: your app secure?
Lovable, di platform, and di app wey you build on am, dem dey secure dem separately. Lovable dey scan for common mistakes, but your app safe only as im own access rules, keys and server code. Check say row-level security dey on for every exposed table and e match who fit see wetin, say no secret key dey reach di browser, say di server dey confirm payments, and say somebody dey watch di live app.
- Wetin dey behind CVE-2025-48757
- Row-level security off, or e too wide
- Safe to ship
- Supabase publishable (anon) key
- Never ship am
- Service role or other secret keys
- Check again
- After every change wey touch data or access
Lovable secure, and dat one dey make my app secure?
Lovable talk say e dey support SOC 2 and GDPR requirements and e dey publish im security documentation for im trust center. Dat one cover Lovable platform: im infrastructure, im access controls, im staff. E no cover di rules inside your app, because na you (with Lovable help) write those ones.
Lovable security scan dey run quick check every time you publish: database review, dependency audit and MCP server check. Deeper scan, wey you go start by hand (or on schedule, for Lovable Enterprise customers), also dey review access control, unauthenticated endpoints, injection, leaked secrets, payments, authentication and personal data wey dey exposed. Lovable own documentation clear say these tools no fit guarantee complete security. Take di scan as smoke alarm, no be inspection.
Wetin be CVE-2025-48757, and e affect my app?
CVE-2025-48757, wey dem publish for May 2025, dey describe row-level security policies wey no reach for Lovable-generated sites up to 15 April 2025 wey allow unauthenticated attackers read or write database tables. Di US National Vulnerability Database list am with critical CVSS 3.1 score of 9.3 and e note say Lovable dispute am, because each customer dey responsible to protect their own app data.
Di researcher wey report am, Matt Palmer, talk say e scan 1,645 projects and find 303 vulnerable endpoints across 170 of dem, and say Lovable ship im security scan with Lovable 2.0 for April 2025. Whatever view you get about di dispute, di practical lesson na di same: if dem generate your app before then, or if you don change tables since, check your policies by yourself. Policy wey dey no be di same as policy wey correct.
Wetin Lovable security checklist suppose cover?
| Check | Why e matter | How to test am |
|---|---|---|
| RLS on for every table inside exposed schema | Without am, Supabase dey allow any role wey get grant read and write di whole table | Run Supabase Security Advisor; lint 0013 (rls_disabled_in_public) dey flag am |
| Policies match your rules | Policy like USING (true) go pass scan and still allow everybody pass | Sign in as user A, request user B rows through di API, expect say nothing go come back |
| Tables wey get RLS but no policy | Dem dey deny everything, wey dey show as broken feature, no be leak | Advisor lint 0008 (rls_enabled_no_policy); then write di policy wey di feature need |
| No secret keys inside di browser | Di service role key dey bypass every RLS policy | Search di built JavaScript for sb_secret_ or legacy service_role key; rotate any key wey don ever ship |
| Server-side checks on anything wey dey cost money | Di person wey dey use client code fit edit am | Call your edge function directly with price or plan wey you change and expect refusal |
| Rate limiting on sign-up, sign-in and AI calls | Requests wey no get limit dey turn to abuse or surprise bill | Against staging, script 100 quick requests and confirm say dem refuse most |
| Leaked-password protection and MFA for admins | Passwords wey people reuse from other breaches na common way to enter | Try password wey dem don breach before for sign-up |
| Audit log and error monitoring | You no fit investigate wetin you no record | Make admin change for staging and find am for di log |
How I go fix Supabase RLS errors for Lovable app?
RLS errors dey come two opposite kinds, and e go help you to know which one you get.
- Permission denied (Postgres error 42501, or empty result). RLS dey on and no policy allow di request. Na RLS dey work be dat. Write di narrowest policy wey go make di feature work, for example rows where di owner column equal di signed-in user ID.
- Everything dey work for everybody. Dis one na di more dangerous case. Policy like USING (true), or RLS switch wey no dey, dey allow any user pass. Supabase advisor dey flag permissive policies (lint 0024, permissive_rls_policy) and policies wey dey while RLS off (lint 0007, policy_exists_rls_disabled).
- Policies wey dey read user metadata. Supabase dey warn against policies wey base on metadata wey user fit edit by imself (lint 0015, rls_references_user_metadata). Use table wey your server dey control, like team membership table, instead.
When you ask Lovable to fix policy, run di two-user test again after. Prompt wey make error disappear fit do am by widening access, wey be exactly di failure wey you dey try prevent.
Which keys safe to expose for Lovable app?
Supabase documentation talk say di publishable (anon) key safe to expose, because e fit only reach wetin row-level security allow. Secret key, including di service role key, dey bypass every RLS policy and e must never enter browser, app wey dem ship or source control. Di glossary entry on anon key and service role key dey explain di difference. Third-party secrets, like Stripe or email provider keys, belong inside edge function secrets, no be inside di app code. See secrets management.
How often you suppose check live Lovable app again?
After every change wey touch data, access or payments, and on schedule for everything else: dependencies dey get new vulnerabilities, you suppose rotate keys, and new tables dey come with new policies. Na why security dey work better as habit than audit. On our plans, security checks, code review and regression tests dey run on every change before e reach production, and engineer wey no be di author dey approve am.
Questions wey people dey ask well-well
Lovable safe to use for real business app?
Lovable na reasonable place to build and shape app, and e dey scan for common security mistakes. Whether di finished app safe depend on im own access rules, keys and server code, wey you suppose verify before real users and real data land. Lovable documentation talk say im scans no fit guarantee complete security.
Di Supabase anon key inside my Lovable app na security problem?
No. Supabase document di publishable (anon) key as safe to expose, because e fit only reach wetin row-level security allow. E go become problem only when RLS off or e too wide. Di service role key different: e dey bypass RLS and e must never dey inside di browser.
CVE-2025-48757 still dey affect Lovable apps?
Di CVE cover Lovable-generated sites up to 15 April 2025, and Lovable dispute am. Lovable don add security scan since then. Any app, old or new, fit still ship policy wey too wide, so test your own tables with two user accounts instead of depending on di date.
How much Lovable security review dey cost?
Plenty freelancers and firms dey sell one-time reviews for fixed price. On Plutonapps plan, security checks and code review dey run on every change as part of di monthly price, together with building, testing, releasing and running di app. Plans and prices dey our pricing page.
I fit run di security checks by myself?
Yes. Lovable dey run im quick scan when you publish, Supabase Security Advisor dey inside your project dashboard, and di two-user test for di checklist need only two test accounts. Wetin hard to do alone na to continue to do am on every change, as long as di app dey live.
