/**
 * Proof of Concept for CVE-2025-69366
 * This script demonstrates SQL injection in Emerce Core plugin <= 1.8
 * Since exact endpoint and parameter names are unavailable from metadata,
 * this PoC tests common WordPress plugin patterns.
 * Assumptions:
 * 1. Vulnerability exists in an AJAX handler or REST endpoint
 * 2. Plugin uses 'emerce_core' or similar prefix for actions
 * 3. Parameter vulnerable to SQL injection accepts numeric or string input
