At a glance
CVE-2026-2296 is a high-severity Improper Control of Generation of Code ('Code Injection') vulnerability in the Product Addons for Woocommerce WordPress plugin, affecting versions <= 3.1.0. 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 Shop Manager level or above. The issue is fixed in version 3.1.1; sites on affected versions should update now. Disclosed February 2026, reported by Phap Nguyen Anh.
Vulnerability Overview
The Product Addons for Woocommerce – Product Options with Custom Fields plugin for WordPress is vulnerable to Code Injection in all versions up to, and including, 3.1.0. This is due to insufficient input validation of the 'operator' field in conditional logic rules within the evalConditions() function, which passes unsanitized user input directly to PHP's eval() function. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to inject and execute arbitrary PHP code on the server via the conditional logic 'operator' parameter when saving addon form field rules.
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-94: Improper Control of Generation of Code ('Code Injection')
Product Addons for Woocommerce <= 3.1.0 carries this weakness at operator, and reaching it takes an account at Shop Manager level or above. Code injection means input from a request reaches a language construct that evaluates code, so the attacker's text is executed rather than treated as data.
The injected code runs with the web server's privileges, giving the attacker the same access to the database and filesystem as WordPress itself. For Product Addons for Woocommerce the fix is 3.1.1: builds <= 3.1.0 are affected, anything from 3.1.1 onward is not.
Remediation
Update to version 3.1.1, or a newer patched version
How does WordSec protect against this?
An attacker needs Shop Manager 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. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Product Addons for Woocommerce 3.1.1 closes this, and updating the plugin is the step that ends it.
