We take the security of DatabaseKit and our users' data seriously. This document outlines our security practices and how to report vulnerabilities.

We provide security updates for the following versions:

Recommendation: Always use the latest version to ensure you have the latest security patches.

If you discover a security vulnerability, please do NOT file a public issue.

Instead, report it privately to our security team:

📧 info@ciscod.com

Or use GitHub's private vulnerability reporting:

1. Go to the Security tab
2. Click "Report a vulnerability"
3. Fill out the form with details

Please provide as much information as possible:

• Description of the vulnerability
• Steps to reproduce the issue
• Affected versions of DatabaseKit
• Potential impact assessment
• Proof of concept code (if applicable)
• Suggested fix (if you have one)

// ✅ DO: Use environment variablesconstconfig={type: 'postgres',connectionString: process.env.DATABASE_URL,};// ❌ DON'T: Hardcode credentialsconstconfig={type: 'postgres',connectionString: 'postgresql://admin:password123@localhost/mydb',};

1. Use SSL/TLS in production:

   postgresql://user:pass@host:5432/db?sslmode=require
   mongodb+srv://user:pass@cluster.mongodb.net/db?ssl=true
   

2. Rotate credentials regularly

3. Use read-only users where possible

4. Limit network access via firewall rules

// ✅ DO: Let the library handle parameterizationawaitrepo.findAll({user_id: userId});// ❌ DON'T: Interpolate user input into queriesawaitrepo.findAll({name: `%${userInput}%`});// Risky!

// ✅ DO: Explicitly whitelist columnsconstrepo=db.createPostgresRepository({table: 'users',columns: ['id','name','email'],// Only these columns are queryable});// ❌ DON'T: Allow all columns (unless necessary)constrepo=db.createPostgresRepository({table: 'users',columns: [],// Empty = all columns allowed});

1. Parameterized Queries

   • All queries use parameterized statements
   • Prevents SQL injection in PostgreSQL
   • Prevents NoSQL injection in MongoDB

2. Column Whitelisting

   • Restrict which columns can be queried
   • Prevents unauthorized data access

3. Default Filters

   • Apply automatic filters (e.g., soft delete)
   • Prevents accidental exposure of deleted data

4. Error Sanitization

   • Database exception filter sanitizes error messages
   • Prevents leaking internal details to clients

1. Use Guards for Authorization

   @UseGuards(AuthGuard)
   @Controller('users')exportclassUsersController{}

2. Validate Input with DTOs

   classCreateUserDto{
   @IsString()
   @MinLength(2)name!: string;}

3. Rate Limit API Endpoints

4. Log and Monitor Database Access

Before each release:

• All dependencies updated to latest secure versions
• No hardcoded secrets in codebase
• All user inputs are validated
• Error messages don't expose internals
• Parameterized queries used everywhere
• CHANGELOG documents security fixes
• npm audit shows no critical vulnerabilities
• Tests cover security-sensitive code paths

We use these tools to maintain dependency security:

• npm audit - Regular vulnerability scanning
• Dependabot - Automated dependency updates
• Snyk - Deep dependency analysis

To check your project:

npm audit
npm audit fix

We follow responsible disclosure practices:

1. Do not publicly share vulnerability details until a fix is released
2. Do not exploit vulnerabilities beyond what's needed for investigation
3. Do not access, modify, or delete user data
4. Do not perform denial-of-service testing

We will:

1. Credit your contribution in release notes (unless you prefer anonymity)
2. Keep you updated on fix progress
3. Coordinate disclosure timing with you

We appreciate security researchers who help keep DatabaseKit secure:

• OWASP Top 10
• Node.js Security Best Practices
• MongoDB Security Checklist
• PostgreSQL Security
• NestJS Security
