At a glance

CVE-2024-32802 is a medium-severity Missing Authorization vulnerability in the Better Messages WordPress plugin, affecting versions <= 2.4.32. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.4.33; sites on affected versions should update now. Disclosed April 2024, reported by Ananda Dhakal.

Vulnerability Overview

The Better Messages – Live Chat for WordPress, BuddyPress, PeepSo, Ultimate Member, BuddyBoss plugin for WordPress is vulnerable to missing authorization in all versions up to, and including, 2.4.32. This is due to the plugin not properly verifying if a user should have access to a chatoom. This makes it possible for unauthenticated attackers to access chat rooms they should not have access to.

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 Better Messages <= 2.4.32 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 Better Messages the fix is 2.4.33: builds <= 2.4.32 are affected, anything from 2.4.33 onward is not.

Remediation

Update to version 2.4.33, 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: Better Messages 2.4.33 closes this, and updating the plugin is the step that ends it.
