## What is CVE-2026-90902?

CVE-2026-90902 is a high-severity SQL injection vulnerability in joomshaper.com Easy Store extension for Joomla, published on 23 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### 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.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)
