security-audit

Act as a senior WordPress plugin developer. Review the DesignSetGo WordPress plugin for best practices, security vulnerabilities, and performance optimization opportunities.

Comprehensive Review Areas

1. Security Audit (Critical)

Analyze all PHP and JavaScript files for security vulnerabilities:

PHP Security Issues:

• • SQL Injection vulnerabilities (improper use of $wpdb, missing prepare())
• • XSS vulnerabilities (missing esc_html, esc_attr, esc_url, wp_kses)
• • CSRF vulnerabilities (missing nonce verification)
• • Arbitrary file inclusion (improper use of require/include)
• • Path traversal vulnerabilities (missing realpath() checks)
• • Capability checks on privileged operations
• • REST API input validation and sanitization
• • Direct file access checks (ABSPATH checks)

JavaScript Security Issues:

• • XSS via innerHTML with unsanitized data
• • URL validation (preventing javascript:, data: URLs)
• • Data attribute sanitization before DOM manipulation
• • Color/numeric value validation before use

Check these critical files:

• •includes/admin/class-global-styles.php - REST API endpoints
• •includes/patterns/class-loader.php - File inclusion
• •includes/class-assets.php - Asset loading
• •src/extensions/*/frontend.js - Frontend JavaScript
• •Any file with $_GET, $_POST, $_REQUEST, get_json_params()

2. Performance Analysis

Asset Loading:

• • Are assets loading from build/ instead of src/?
• • Conditional loading (only load when blocks present)?
• • Asset file size optimization opportunities
• • Unnecessary dependencies being loaded

Database Performance:

• • Transient caching for expensive operations
• • Block/pattern registration optimization
• • Unnecessary queries on every page load

Frontend Performance:

• • JavaScript bundle size and code splitting
• • CSS optimization (remove unused rules, use CSS variables)
• • Lazy loading for videos/images
• • React performance (missing memoization, unnecessary re-renders)

3. WordPress Coding Standards

PHP Standards:

• • Proper DocBlocks for all functions/methods
• • Consistent namespacing
• • Text domains on all translation functions
• • Proper sanitization and escaping
• • Error handling and logging

JavaScript Standards:

• • ESLint compliance
• • Proper JSDoc comments
• • Modern ES6+ patterns
• • WordPress-specific best practices

4. Architecture Review

Code Quality:

• • Singleton pattern properly implemented
• • Separation of concerns
• • DRY principle (no code duplication)
• • File organization and naming conventions
• • No unused/commented code

WordPress Integration:

• • Proper use of hooks and filters
• • Block registration best practices
• • Asset enqueuing best practices
• • Admin page security

Output Requirements

Generate a comprehensive SECURITY-REVIEW.md file containing:

1. Executive Summary

• •Overall security status (🔴 Critical, 🟡 High, 🟢 Medium, 🔵 Low)
• •Number of issues found by severity
• •Quick assessment of production readiness

2. Critical Security Issues (🔴)

For each issue:

• •File location with line numbers
• •Clear description of the vulnerability
• •Attack vector explanation
• •Complete code fix with before/after
• •Estimated fix time

3. High Priority Issues (🟡)

Same format as critical issues

4. Medium Priority - Performance (🟢)

• •Optimization opportunities
• •Expected performance gains
• •Implementation recommendations

5. Low Priority - Code Quality (🔵)

• •Coding standards violations
• •Documentation improvements
• •Refactoring suggestions

6. Action Plan

Organize issues by priority with time estimates:

• •Week 1: Critical security fixes (must do before production)
• •Week 2: High priority security & performance
• •Week 3: Performance optimization
• •Week 4: Code quality & standards

7. Security Checklist for Production

Clear checklist of security requirements before deployment

8. Things Done Well

Positive feedback on good practices to maintain

Execution Steps

1. •

   Review Plugin Structure

   • •Read main plugin file
   • •Identify all PHP classes in includes/
   • •Identify all JavaScript files in src/
2. •

   Security Scan

   • •Search for vulnerable patterns:
     bash

     # PHP vulnerabilities
     grep -r "get_json_params\|require\|include\|\$_GET\|\$_POST" includes/ --include="*.php"
     grep -r "sanitize\|escape\|esc_html\|esc_attr\|wp_kses" includes/ --include="*.php"
     
     # JavaScript vulnerabilities
     grep -r "innerHTML\|getAttribute\|setAttribute" src/ --include="*.js"
     

3. •

   Analyze Each Vulnerability

   • •Read the full context of flagged files
   • •Determine if vulnerability exists
   • •Provide specific fix
4. •

   Performance Review

   • •Check asset loading strategy in includes/class-assets.php
   • •Review build output sizes
   • •Identify optimization opportunities
5. •

   Generate Report

   • •Create comprehensive markdown document
   • •Include code examples for all fixes
   • •Provide actionable recommendations

Additional Checks

Dependency Security

• • Run npm audit for JavaScript vulnerabilities
• • Run npm run check-licenses for GPL compatibility
• • Check for outdated packages

Build Configuration

• • Verify webpack config is optimized
• • Check that source maps are disabled in production
• • Verify minification is enabled

WordPress.org Readiness

• • No hardcoded credentials or API keys
• • Proper licensing headers
• • No "phone home" functionality
• • Follows WordPress.org guidelines
