Joomla Extension - joomshaper.com - Broken Access Control (ACL Bypass) in ApiController Record Editing in Easy Store extension 1.0.0-3.0.0 - The allowEdit() method in ApiController.php hardcoded return true;, bypassing Joomla component-level and asset-level ACL permission checks. Any authenticated backend user could edit any EasyStore record, regardless of specific ACL permission grants. Resolved by replacing the hardcoded boolean with proper ACL authorization checks via AccessControl::create()->canEdit().

Joomla Extension - joomshaper.com - Authenticated, Privileged SQL Injection in Media Image Deletion in Easy Store extension 1.0.0-3.0.0 - The checkout.searchGuestUser endpoint allowed querying guest checkout records solely by supplying an email address. The server returned complete shipping details (full name, phone number, street address, city, postal code, and country) directly from the #easystoreguests table with no authentication, session validation, or ownership checks. An unauthenticated attacker could iterate through email lists to enumerate guest customers and harvest sensitive Personally Identifiable Information (PII). Resolved by removing the unauthenticated server-side guest lookup endpoint entirely and migrating autofill functionality to client-side localStorage protected by explicit user consent.

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().

Joomla Extension - joomshaper.com - Missing CSRF and Access Control on Site Configuration Update in Easy Store extension 1.0.0-3.0.0 - The endpoint administrator/index.php?option=comeasystore&task=appconfig.updateConfiguration updated core Joomla mail configuration (fromname, mailfrom) in configuration.php without verifying anti-CSRF tokens or checking for administrative permissions (canAdmin). A malicious site could silently modify the site's sender name and email address via forged requests from an admin's browser. Resolved by enforcing Session::checkToken('request') / Session::checkToken('post') and adding explicit administrative authorization verification via AccessControl::create()->canAdmin().

Joomla Extension - joomshaper.com - Authenticated, Privileged SQL Injection in Coupon Bulk Update in Easy Store extension 1.0.0-3.0.0 - The coupon bulk update task (administrator/index.php?option=comeasystore&task=coupon.couponBulkUpdate) took input IDs and directly concatenated them into raw SQL IN (...) clauses in ProductCoupon.php and CouponsModel.php without sanitization or parameterization. An authenticated administrator could manipulate the query through injected SQL syntax. Resolved by strictly casting all IDs to integers (arraymap('intval', ...)) and adopting parameterized ->whereIn() query construction.

Joomla Extension - joomshaper.com - Missing CSRF Token Verification in Storefront Product Review Submission in Easy Store extension 1.0.0-3.0.0 - The product review submission endpoint (index.php?option=comeasystore&task=product.addReview) accepted submissions without verifying an anti-CSRF token (the check had been commented out in code). An attacker could trick a logged-in user into posting unauthorized reviews or submitting review spam via cross-site requests. Resolved by enforcing Session::checkToken('request') / Session::checkToken('post') in ProductController, injecting HTMLHelper::('form.token') into the review form template, and appending the session token to the submission payload in review-form.js.

Joomla Extension - joomshaper.com - Unauthenticated PII Exposure via IDOR in Guest Checkout in Easy Store extension 1.0.0-3.0.0 - The checkout.searchGuestUser endpoint allowed querying guest checkout records solely by supplying an email address. The server returned complete shipping details (full name, phone number, street address, city, postal code, and country) directly from the #easystoreguests table with no authentication, session validation, or ownership checks. An unauthenticated attacker could iterate through email lists to enumerate guest customers and harvest sensitive Personally Identifiable Information (PII). Resolved by removing the unauthenticated server-side guest lookup endpoint entirely and migrating autofill functionality to client-side localStorage protected by explicit user consent.
