## Overview

Joomla Extension - joomshaper.com - Missing CSRF Token Verification across Administrator AJAX API Endpoints in Easy Store extension 1.0.0-3.0.0 - The administrator ApiController only validated CSRF tokens inside the products() action. All other administrative AJAX endpoints (orders, coupons, media, customers, settings, tags, categories, reviews, and collections) accepted state-changing requests without checking anti-CSRF tokens. An attacker could trick a logged-in administrator into triggering unauthorized state modifications across the store backend. Resolved by implementing global CSRF verification in ApiController::execute() for all state-changing HTTP methods (POST, PUT, PATCH, DELETE) via Session::checkToken().
