Bolt.new Security Checklist
Last updated: January 12, 2026
Use this checklist to ensure your Bolt.new 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 Bolt.new 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 Bolt.new 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.

Run Automated Security ScanFrequently Asked Questions
Why does Bolt need a different checklist than other platforms?
Bolt generates complete applications including backend code, which introduces code-level security concerns (source maps, hardcoded secrets in generated code) that pure frontend builders don't have. The checklist addresses both generated code review and infrastructure security.
Should I review all AI-generated code manually?
Yes, at minimum review authentication flows, database queries, and any code handling sensitive data. AI tools prioritize functionality over security. VAS can automate detection of common issues, but understanding your auth flow requires human review.
