At a glance
CVE-2025-11164 is a medium-severity Missing Authorization vulnerability in the Mavix Education WordPress theme, affecting versions <= 1.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 1.1; sites on affected versions should update now. Disclosed December 2025, reported by Jonas Benjamin Friedli.
Vulnerability Overview
The Mavix Education theme for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'mavix_education_activate_plugin' AJAX action in all versions up to, and including, 1.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to activate the Creativ Demo Importer plugin.
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.
CWE-862: Missing Authorization
Mavix Education <= 1.0 carries this weakness at mavix_education_activate_plugin, and reaching it takes an account at Subscriber level or above. 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 Mavix Education the fix is 1.1: builds <= 1.0 are affected, anything from 1.1 onward is not.
Remediation
Update to version 1.1, 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: Mavix Education 1.1 closes this, and updating the theme is the step that ends it.
