Security Audit

Please perform a comprehensive security audit of this codebase:

1. Secrets and Credentials Scan

Search for exposed sensitive information:

# Common patterns for secrets
chs find-code "password\s*=\s*['\"]|api_key\s*=\s*['\"]|secret\s*=\s*['\"]"
chs find-code "token\s*=\s*['\"]|private.*key\s*=|aws_.*=\s*['\"]"

# Environment files
chs find-file "\.env*" 
# Check if .env files are in .gitignore!

# Common secret file names
chs find-file "*secret*\|*credential*\|*private*"

2. Injection Vulnerabilities

SQL Injection

# String concatenation in queries
chs find-code "query.*\+.*\|\".*SELECT.*\+\|\".*INSERT.*\+\|\".*UPDATE.*\+"

# Direct variable interpolation
chs find-code "query.*\$\{.*\}|query.*\${.*}"

Command Injection

# Dangerous functions
chs find-code "exec\(|spawn\(|system\(|eval\("

# Shell command building
chs find-code "shell.*\+\|cmd.*\+\|exec.*\$"

Path Traversal

# Path manipulation
chs find-code "\.\./\|\.\.\\\\|\.\./\.\."
chs find-code "path\.join.*req\.|path\.join.*user"

3. Authentication & Authorization

Find Auth Code

chs find-code "auth\|login\|session\|jwt\|token"
chs find-file "*auth*\|*login*\|*session*"

Check for Issues

• Hardcoded credentials
• Weak password requirements
• Missing authorization checks
• Session fixation risks
• Insecure token storage

4. Data Validation & Sanitization

# Find user input handling
chs find-code "req\.body\|req\.query\|req\.params"

# Check for validation
chs find-code "validate\|sanitize\|escape"

# Dangerous operations without validation
chs find-code "innerHTML\|dangerouslySetInnerHTML"

5. Dependencies Security

# Run security audits
ch ts audit  # For npm projects

# Check for known vulnerable packages
chs find-code "require\(|import.*from" | grep -E "(lodash|moment|axios|express)" 
# Then check versions against known vulnerabilities

6. HTTPS & Security Headers

# Check for HTTP usage
chs find-code "http://|createServer\(|\.listen\("

# Security headers
chs find-code "helmet\|cors\|csp\|x-frame-options"

7. Error Handling & Information Disclosure

# Stack traces in production
chs find-code "stack\|stackTrace|error\.stack"

# Detailed error messages
chs find-code "catch.*console\.|catch.*res\.send"

8. Generate Security Report

Critical Issues (Fix Immediately)

• Exposed secrets or credentials
• SQL/Command injection vulnerabilities
• Missing authentication

High Priority (Fix Soon)

• Outdated dependencies with known vulnerabilities
• Weak authentication mechanisms
• Missing input validation

Medium Priority (Plan to Fix)

• Missing security headers
• Verbose error messages
• Insecure defaults

Recommendations

• Specific fixes for each issue
• Security best practices to implement
• Tools and libraries to adopt

Focus on exploitable vulnerabilities that could lead to data breaches!
