Vulnerability Overview
The SMS for WooCommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.8.1. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
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 privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in SMS for WooCommerce <= 2.8.1 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For SMS for WooCommerce the fix is 2.8.1.1: builds <= 2.8.1 are affected, anything from 2.8.1.1 onward is not.
Remediation
Update to version 2.8.1.1, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to SMS for WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: SMS for WooCommerce 2.8.1.1 closes this, and updating the plugin is the step that ends it.
