Base44 Security Checklist
Last updated: January 12, 2026
Use this checklist to ensure your Base44 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 Base44 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 Base44 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.

- Data validation requirements
- Third-party integration security
Secret Management
Remove hardcoded API keys from generated code
AutoBase44 generates code with API keys inline — search for 'sk-', 'apiKey', 'api_key' and move all to env vars
Use server-side environment variables
All secrets (OpenAI, Stripe, database credentials) must be in server-side env vars, not frontend code
Add .env to .gitignore
Prevent environment files from being committed to version control
Use separate keys per environment
Don't reuse production API keys in development or staging
AI-Generated Code Review
Review generated authentication flows
Base44's prompt-to-code generation often creates auth without rate limiting or account lockout
Check for authorization in API routes
Generated endpoints may check authentication but skip authorization — verify users can only access their own data
Validate server-side input handling
AI-generated code often trusts user input — add validation with zod or joi on every endpoint
Audit generated database queries
Check for SQL injection, missing parameterized queries, and unscoped data access in generated code
Disable source maps in production
AutoDon't expose original generated code via source maps
Deployment Security
Verify HTTPS is enforced
AutoEnsure all traffic is served over HTTPS with proper TLS configuration
Remove debug endpoints
Base44 may generate debug/test routes — remove before production deployment
Configure CORS for your domain only
AutoRestrict Access-Control-Allow-Origin to your actual domain, not '*'
HTTP Security
Add Content-Security-Policy
AutoPrevent XSS and injection attacks in generated frontend code
Enable HSTS
AutoForce HTTPS connections
Set X-Frame-Options
AutoPrevent clickjacking attacks
Configure X-Content-Type-Options
AutoPrevent MIME sniffing

How do I find exposed secrets in Base44 apps?
Search your codebase for common key patterns: 'sk-' (OpenAI), 'sk_live' (Stripe), 'api_key', and 'password'. Base44's prompt-to-code generation often embeds these directly in frontend JavaScript. Move all secrets to server-side environment variables.
Does Base44 generate secure authentication code?
Base44 generates functional auth flows but typically skips rate limiting, account lockout, and proper session management. Always review generated auth code manually and add brute-force protections before going to production.
What should I check before launching a Base44 app?
1) All API keys moved to environment variables, 2) Authentication code reviewed for rate limiting and authorization checks, 3) Input validation added to every API endpoint, 4) Security headers configured, 5) Source maps disabled in production.
