At a glance
CVE-2022-4872 is a critical-severity Missing Authorization vulnerability in the WooCommerce Chained Products WordPress plugin, affecting versions < 2.12.0. It carries a CVSS score of 9.1 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.12.0; sites on affected versions should update now. Disclosed January 2023, reported by WPScanTeam.
Vulnerability Overview
The WooCommerce Chained Products plugin for WordPress is vulnerable to authorization bypass due to a missing capability check when updating its settings in versions up to, and including, 2.12.0. This makes it possible for unauthenticated attackers to update arbitrary options that may not belong to the plugin. However, update of options is limited to the value "no".
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. A successful exploit has high impact on integrity, availability.
CWE-862: Missing Authorization
Reaching this weakness in WooCommerce Chained Products < 2.12.0 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 WooCommerce Chained Products the fix is 2.12.0: builds < 2.12.0 are affected, anything from 2.12.0 onward is not.
Remediation
Update to version 2.12.0, 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: WooCommerce Chained Products 2.12.0 closes this, and updating the plugin is the step that ends it.
