CVE-2026-90902: CWE-74 Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') in joomshaper.com Easy Store extension for Joomla
CVE-2026-90902 is a high-severity SQL injection vulnerability in the Easy Store extension for Joomla by joomshaper.com. It affects versions 1.0.0 through 3.0.0. The vulnerability arises from improper sanitization of input IDs used in SQL IN clauses during the coupon bulk update task in the administrator interface. An authenticated administrator can exploit this flaw by injecting malicious SQL syntax, potentially manipulating the database. The issue was resolved by casting all IDs to integers and using parameterized queries to prevent injection.
AI Analysis
Technical Summary
The Easy Store extension for Joomla (versions 1.0.0 to 3.0.0) contains an SQL injection vulnerability (CWE-74) in the coupon bulk update functionality accessed via administrator/index.php?option=com_easystore&task=coupon.couponBulkUpdate. The vulnerability occurs because input IDs are concatenated directly into raw SQL IN clauses in ProductCoupon.php and CouponsModel.php without sanitization or parameterization. This allows an authenticated administrator to inject SQL code. The fix involved casting IDs to integers using array_map('intval', ...) and adopting parameterized ->whereIn() query construction to prevent injection.
Potential Impact
An authenticated administrator can exploit this vulnerability to perform SQL injection attacks, potentially leading to unauthorized database manipulation. This could compromise data integrity or confidentiality within the Joomla Easy Store extension environment. The CVSS 4.0 score of 8.2 indicates a high severity impact with network attack vector and high impact on confidentiality.
Mitigation Recommendations
No explicit patch or vendor advisory link is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. The vulnerability was resolved by casting all IDs to integers and using parameterized queries. Administrators should verify that their Easy Store extension is updated to a version that includes these fixes or apply the recommended code changes to prevent SQL injection.
