At a glance

CVE-2022-3400 is a medium-severity Missing Authorization vulnerability in the Bricks WordPress theme, affecting versions 1.0 – 1.5.3. 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 1.5.4; sites on affected versions should update now. Disclosed October 2022.

Vulnerability Overview

The Bricks theme for WordPress is vulnerable to authorization bypass due to a missing capability check on the bricks_save_post AJAX action in versions 1.0 to 1.5.3. This makes it possible for authenticated attackers with minimal permissions, such as a subscriber, to edit any page, post, or template on the vulnerable WordPress website.

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

Reaching this weakness in Bricks 1.0 – 1.5.3 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 Bricks the fix is 1.5.4: builds 1.0 – 1.5.3 are affected, anything from 1.5.4 onward is not.

Remediation

Update to version 1.5.4, 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: Bricks 1.5.4 closes this, and updating the theme is the step that ends it.
