At a glance
CVE-2023-3204 is a medium-severity Missing Authorization vulnerability in the Materialis WordPress theme, affecting versions <= 1.1.24. 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 1.1.30; sites on affected versions should update now. Disclosed June 2024, reported by Gibran Abdillah.
Vulnerability Overview
The Materialis theme for WordPress is vulnerable to limited arbitrary options updates in versions up to, and including, 1.1.24. This is due to missing authorization checks on the companion_disable_popup() function called via an AJAX action. This makes it possible for authenticated attackers, with minimal permissions such as subscribers, to modify any option on the site to a numerical value.
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
Materialis <= 1.1.24 carries this weakness at companion_disable_popup(), and reaching it 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 Materialis the fix is 1.1.30: builds <= 1.1.24 are affected, anything from 1.1.30 onward is not.
Remediation
Update to version 1.1.30, 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: Materialis 1.1.30 closes this, and updating the theme is the step that ends it.
