At a glance

This record tracks a low-severity Improper Authorization vulnerability in the Abandoned Cart Lite for WooCommerce WordPress plugin, affecting versions < 5.16.1. It carries a CVSS score of 3.1 (reachable over the network). The issue is fixed in version 5.16.1; sites on affected versions should update now. Disclosed November 2023.

Vulnerability Overview

The Abandoned Cart Lite for WooCommerce plugin for WordPress is vulnerable to unauthorized loss of data due to invalid logic in the capability check present in the wcal_delete_expired_used_coupon_code function in all versions up to and including 5.16.0. This makes it possible for authenticated attackers with subscriber privileges or above to delete expired used coupon codes, granted they are able to obtain a nonce via a separate vulnerability.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user.

CWE-285: Improper Authorization

Reaching this weakness in Abandoned Cart Lite for WooCommerce < 5.16.1 takes a caller who can reach the endpoint. Improper authorization means a permission check exists but does not cover the case being exercised, so a caller who is allowed to do one thing is allowed to do a neighbouring thing as well.

A lower-privileged account performs an action reserved for a higher one, which on a multi-author or membership site means an ordinary user reaching administrative behaviour. For Abandoned Cart Lite for WooCommerce the fix is 5.16.1: builds < 5.16.1 are affected, anything from 5.16.1 onward is not.

Remediation

Update to version 5.16.1, 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: Abandoned Cart Lite for WooCommerce 5.16.1 closes this, and updating the plugin is the step that ends it.
