At a glance
CVE-2024-10437 is a medium-severity Missing Authorization vulnerability in the WPC Smart Messages for WooCommerce WordPress plugin, affecting versions <= 4.2.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 4.2.2; sites on affected versions should update now. Disclosed October 2024, reported by Francesco Carlucci.
Vulnerability Overview
The WPC Smart Messages for WooCommerce plugin for WordPress is vulnerable to unauthorized Smar Message activation/deactivation due to a missing capability check on the ajax_enable function in all versions up to, and including, 4.2.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to activate or deactivate smart messages.
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.
CWE-862: Missing Authorization
Reaching this weakness in WPC Smart Messages for WooCommerce <= 4.2.1 takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For WPC Smart Messages for WooCommerce the fix is 4.2.2: builds <= 4.2.1 are affected, anything from 4.2.2 onward is not.
Remediation
Update to version 4.2.2, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: WPC Smart Messages for WooCommerce 4.2.2 closes this, and updating the plugin is the step that ends it.
