At a glance

CVE-2020-36714 is a high-severity Improper Authorization vulnerability in the Brizy WordPress plugin, affecting versions < 1.0.126. It carries a CVSS score of 7.4 (reachable over the network; low attack complexity). The issue is fixed in version 1.0.126; sites on affected versions should update now. Disclosed June 2020, reported by Jerome Bruandet.

Vulnerability Overview

The Brizy plugin for WordPress is vulnerable to authorization bypass due to a incorrect capability check on the is_administrator() function in versions up to, and including, 1.0.125. This makes it possible for authenticated attackers to access and interact with available AJAX functions.

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-285: Improper Authorization

Brizy < 1.0.126 carries this weakness at is_administrator(), and reaching it takes a caller who can reach the endpoint. Improper authorization means a permission check exists but does not cover the case being exercised, so a caller who is allowed to do one thing is allowed to do a neighbouring thing as well.

A lower-privileged account performs an action reserved for a higher one, which on a multi-author or membership site means an ordinary user reaching administrative behaviour. For Brizy the fix is 1.0.126: builds < 1.0.126 are affected, anything from 1.0.126 onward is not.

Remediation

Update to version 1.0.126, 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: Brizy 1.0.126 closes this, and updating the plugin is the step that ends it.
