At a glance

This record tracks a medium-severity Missing Authorization vulnerability in the WebberZone Top 10 WordPress plugin, affecting versions <= 3.2.4. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 3.2.5; sites on affected versions should update now. Disclosed February 2023.

Vulnerability Overview

The Top 10 – Popular posts plugin for WordPress is vulnerable to insufficient access control in the 'tptn_chart_data' AJAX action in versions up to, and including, 3.2.4. This allows authenticated attackers to access chart data granted they can access the admin dashboard and retrieve the nonce used for access control.

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

WebberZone Top 10 <= 3.2.4 carries this weakness at tptn_chart_data, and reaching it 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 WebberZone Top 10 the fix is 3.2.5: builds <= 3.2.4 are affected, anything from 3.2.5 onward is not.

Remediation

Update to version 3.2.5, 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: WebberZone Top 10 3.2.5 closes this, and updating the plugin is the step that ends it.
