Official description

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=com_easystore&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 (array_map('intval', ...)) and adopting parameterized ->whereIn() query construction.
