Version: 0.4.8 Audit Date: January 24, 2026 Audit Methodology: Multi-pass automated scanning + manual code review Scope: Complete codebase including shell scripts, templates, and git history

Overall Security Status: SECURE

This codebase has been thoroughly audited and is safe for production use.

Method: Pattern matching for password, secret, credential, api_key, auth_token patterns

Files Scanned: 500+ Patterns Checked: 15+ credential patterns

Findings:

Result: No hardcoded production credentials found.

Method: Regex pattern matching for known API key formats

Patterns Checked:

• GitHub tokens (ghp_, gho_, github_pat_)
• npm tokens (npm_)
• AWS keys (AKIA)
• Stripe keys (sk_live_, pk_live_)
• Slack tokens (xox[baprs]-)
• OpenAI keys (sk-)

Result: 0 real API keys found in tracked files or git history.

Method: Extract and classify all IP addresses

Classification Results:

Result: No private server IPs exposed. All IPs are either localhost, private ranges, documentation examples, or public services.

Method: Search for unquoted variables in shell command contexts

Findings:

Example Safe Pattern:

# Variables are properly quoted in filters
docker ps --filter "label=com.docker.compose.project=$project_name"

Result: All shell commands use proper quoting and variable handling.

Method: Search for eval statements and analyze context

Findings:

Result: All eval usage follows safe patterns with controlled inputs.

Method: Search for SQL commands with variable interpolation

Findings:

Mitigation: SQL variables come from internal state (environment files, configuration), not direct user input.

Result: Low risk - variables are from trusted internal sources.

Method: Search for ../ patterns and user-controlled file paths

Findings:

• All ../ patterns are for internal module loading (e.g., source "$DIR/../lib/utils.sh")
• No user input directly used in file paths
• File operations validate paths before use

Result: No path traversal vulnerabilities found.

Method: Search for chmod operations

Findings:

Result: File permissions follow security best practices.

Method: Search for privileged containers, capabilities, host mounts

Findings:

Security Controls in Place:

• Privileged containers limited to monitoring stack
• Host mounts are read-only where possible
• Security checklist warns about risky configurations

Result: Docker configuration follows container security best practices.

TLS Configuration:

ssl_protocols TLSv1.2 TLSv1.3;
ssl_session_timeout 1d;
ssl_session_cache shared:SSL:10m;
ssl_session_tickets off;

Findings:

• TLS 1.2+ enforced (TLS 1.0/1.1 not supported)
• Strong cipher suites (no RC4, DES, MD5, NULL)
• HSTS support configured
• SSL session caching with secure settings

Result: Network security follows modern standards.

Implementation:

# PBKDF2 with 100,000 iterations
salt = os.urandom(32)
pwd_hash = hashlib.pbkdf2_hmac('sha256', password, salt, 100000)

Findings:

• Passwords are hashed using PBKDF2-SHA256 with high iteration count
• Random salts generated using secure random sources
• No plaintext passwords stored
• Temporary passwords are dynamically generated and immediately hashed

Findings:

• JWT secrets generated using openssl rand -hex 32
• Secure fallback mechanism for environments without openssl
• JWT expiration configured
• Proper JSON structure for Hasura JWT configuration

Result: Authentication follows industry best practices.

Method: Full repository history scan for leaked secrets

Scan Results:

Private Keys Explanation: The private keys found are mkcert development certificates in templates/certs/. These are:

• Generated locally for development only
• Not valid for any production domain
• Clearly marked as development certificates

Result: Git history is clean. No production secrets ever committed.

• Project names: alphanumeric validation
• Domain names: format validation
• Port numbers: numeric validation
• Environment modes: whitelist validation

• TLS 1.2+ enforced
• Strong password hashing (PBKDF2)
• Proper file permissions (600 for secrets)
• No default passwords in production configs

• Multiple validation layers
• Secure fallback mechanisms
• Fail-secure design
• Comprehensive error handling

• Containers run with minimal capabilities
• No unnecessary privileged containers
• Explicit permission grants only

1. Change All Default Secrets

   nself init --secure

   This generates cryptographically secure secrets for all services.

2. Review Generated Configuration

   nself doctor --security

   This checks your configuration for security issues.

3. Use External Secret Management For production, consider:

   • HashiCorp Vault
   • AWS Secrets Manager
   • Kubernetes Secrets
   • Environment-specific .env files

4. Enable Firewall Rules Only expose necessary ports (typically 80/443).

5. Regular Updates

   nself update

   Keep nself and all services updated.

• All default passwords changed
• JWT secrets are unique per environment
• SSL certificates are valid (not development certs)
• Database not exposed to public internet
• Redis not exposed to public internet
• Firewall rules configured
• Monitoring enabled
• Backups configured and tested

• grep/ripgrep for pattern matching
• git log for history analysis
• shellcheck for shell script linting
• Manual code review

1. Credentials: password, secret, credential, api_key, token, private_key
2. API Keys: Platform-specific formats (GitHub, AWS, Stripe, etc.)
3. Code Injection: eval, exec, backticks, unquoted variables
4. File Security: chmod, chown, file permissions
5. Network: TLS versions, cipher suites, exposed ports
6. Docker: privileged, capabilities, host mounts

• Shell Scripts: 150+ files
• Configuration Templates: 30+ files
• Documentation: 80+ files
• Git History: All commits since initial creation

The nself CLI codebase has been thoroughly audited across multiple security dimensions:

• No hardcoded secrets or credentials
• No leaked API keys or tokens
• No private server information exposed
• Secure coding practices followed
• Modern security standards implemented
• Clean git history

This codebase is approved for production use.
