At a glance

CVE-2024-33944 is a medium-severity Missing Authorization vulnerability in the AWeber for WooCommerce WordPress plugin, affecting versions <= 4.0.2. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 4.0.3; sites on affected versions should update now. Disclosed April 2024, reported by Dave Jong.

Vulnerability Overview

The WooCommerce AWeber Newsletter Subscription plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on a function in all versions up to, and including, 4.0.2. This makes it possible for unauthenticated attackers to reset and change the plugin's access token.

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, and no interaction from a victim user.

CWE-862: Missing Authorization

Reaching this weakness in AWeber for WooCommerce <= 4.0.2 takes a caller who can reach the endpoint. 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 AWeber for WooCommerce the fix is 4.0.3: builds <= 4.0.2 are affected, anything from 4.0.3 onward is not.

Remediation

Update to version 4.0.3, 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: AWeber for WooCommerce 4.0.3 closes this, and updating the plugin is the step that ends it.
