At a glance
CVE-2024-9756 is a medium-severity Missing Authorization vulnerability in the Order Attachments for WooCommerce WordPress plugin, affecting versions 2.0 – 2.4.1. 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 2.5.0; sites on affected versions should update now. Disclosed October 2024, reported by lucky_noob.
Vulnerability Overview
The Order Attachments for WooCommerce plugin for WordPress is vulnerable to unauthorized limited arbitrary file uploads due to a missing capability check on the wcoa_add_attachment AJAX action in versions 2.0 to 2.4.1. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload limited file types.
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 Order Attachments for WooCommerce 2.0 – 2.4.1 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 Order Attachments for WooCommerce the fix is 2.5.0: builds 2.0 – 2.4.1 are affected, anything from 2.5.0 onward is not.
Remediation
Update to version 2.5.0, 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: Order Attachments for WooCommerce 2.5.0 closes this, and updating the plugin is the step that ends it.
