Vulnerability Overview
The MB Custom Post Types & Custom Taxonomies plugin for WordPress is vulnerable to unauthorized access in versions 2.0.2 through 2.12.2. This is due to a missing capability check on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action.
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.
CWE-862: Missing Authorization
Reaching this weakness in MB Custom Post Types & Custom Taxonomies 2.0.2 – 2.12.2 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 MB Custom Post Types & Custom Taxonomies the fix is 2.12.3: builds 2.0.2 – 2.12.2 are affected, anything from 2.12.3 onward is not.
Remediation
Update to version 2.12.3, 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: MB Custom Post Types & Custom Taxonomies 2.12.3 closes this, and updating the plugin is the step that ends it.
