At a glance
CVE-2026-2019 is a high-severity Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') vulnerability in the CartSuite WordPress plugin, affecting versions <= 1.1.21. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Administrator level or above. The issue is fixed in version 1.1.22; sites on affected versions should update now. Disclosed February 2026, reported by Phap Nguyen Anh.
Vulnerability Overview
The Cart All In One For WooCommerce plugin for WordPress is vulnerable to Code Injection in all versions up to, and including, 1.1.21. This is due to insufficient input validation on the 'Assign page' field which is passed directly to the eval() function. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute arbitrary PHP code on the server.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
Remediation
Update to version 1.1.22, or a newer patched version
How does WordSec protect against this?
An attacker needs Administrator access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: CartSuite 1.1.22 closes this, and updating the plugin is the step that ends it.
