Lovable Security Checklist
Last updated: January 12, 2026
Use this checklist to ensure your Lovable application is secure before launch. 5 critical items require immediate attention.
Why This Security Checklist Matters
Security checklists serve as systematic guides for identifying vulnerabilities that might otherwise be overlooked during rapid development cycles. For Lovable applications specifically, this checklist addresses the most common security gaps that emerge when using AI-assisted development workflows.
Research from multiple security organizations indicates that approximately 80% of AI-built applications contain at least one exploitable vulnerability at launch. The vulnerabilities are often predictable—they follow patterns that this checklist is designed to catch. By systematically reviewing each item, you significantly reduce the risk of launching an insecure application.
Unlike generic security checklists, this guide focuses specifically on vulnerabilities prevalent in Lovable applications. Each item has been prioritized based on real-world attack patterns and the potential impact of exploitation. Critical items should be addressed before any production deployment.
Critical Priority
Critical items can lead to complete application compromise, data breaches, or unauthorized access to all user accounts. These must be addressed before deploying to production. Attackers actively scan for these vulnerabilities.
High Priority
High priority items represent significant security risks that could allow unauthorized access to sensitive data or functionality. While not immediately catastrophic, these vulnerabilities should be fixed as soon as possible.
Medium/Low Priority
Medium and low priority items strengthen your overall security posture. While they may not be immediately exploitable, addressing them prevents attack chains and defense-in-depth gaps.
Manual vs Automated Security Checking
While manual security reviews are thorough, they're time-consuming and prone to human error. Automated scanning catches common vulnerabilities instantly, freeing you to focus on business logic and complex security decisions.
Items VAS Automates
- Exposed API keys and secrets in JavaScript bundles
- HTTP security header configuration
- Supabase RLS policy testing
- Firebase Security Rules validation
- Cookie security attributes
Manual Review Still Required
- Business logic vulnerabilities
- Custom authentication implementations
- Access control logic in API routes
- Data validation requirements
- Third-party integration security
Database Security

How many checklist items can VAS automatically verify?
VAS can automatically check 11 of the 14 items on the Lovable security checklist, including all RLS configurations, exposed API keys, security headers, and authentication settings. The remaining 3 items require manual verification.
Which Lovable checklist items are most critical?
The 7 critical items are all related to database security (RLS policies) and secret management. Missing RLS was the root cause of CVE-2025-48757, which affected 170+ Lovable apps. Start with these before addressing high/medium items.
How long does it take to complete this checklist?
For a typical Lovable app, expect 30-60 minutes for the full checklist. RLS policy writing takes the longest. Running a VAS scan first helps prioritize - it identifies which items are already passing and which need attention.
