At a glance
CVE-2023-23868 is a medium-severity Missing Authorization vulnerability in the Cost of Goods WordPress plugin, affecting versions <= 2.8.6. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 2.8.7; sites on affected versions should update now. Disclosed February 2023, reported by Cat.
Vulnerability Overview
The Cost of Goods for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the save_costs function in versions up to, and including, 2.8.6. This makes it possible for authenticated attackers, with contributor-level permissions and above, to perform an unauthorized edit or save of prices.
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. A successful exploit has high impact on integrity.
CWE-862: Missing Authorization
Reaching this weakness in Cost of Goods <= 2.8.6 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 Cost of Goods the fix is 2.8.7: builds <= 2.8.6 are affected, anything from 2.8.7 onward is not.
Remediation
Update to version 2.8.7, 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: Cost of Goods 2.8.7 closes this, and updating the plugin is the step that ends it.
