WordPress Security & Data Validation

Version: 1.0.0 Target: WordPress 6.7+ | PHP 8.3+ Skill Level: Intermediate to Advanced

Overview

Security is not optional in WordPress development—it's fundamental. This skill teaches the three-layer security model that prevents XSS, CSRF, SQL injection, and other common web vulnerabilities through proper input sanitization, business logic validation, and output escaping.

The Golden Rule: "Sanitize on input, validate for logic, escape on output."

Why This Matters

Every year, thousands of WordPress sites are compromised due to security vulnerabilities in plugins and themes. Most of these attacks exploit one of three weaknesses:

  1. XSS (Cross-Site Scripting): Malicious JavaScript injected through unsanitized output
  2. CSRF (Cross-Site Request Forgery): Unauthorized actions performed on behalf of authenticated users
  3. SQL Injection: Database manipulation through unsanitized database queries
