At a glance

This record tracks a high-severity Improper Privilege Management vulnerability in the Import and export users and customers WordPress plugin, affecting versions 1.15. It carries a CVSS score of 7.7 (reachable over the network; low attack complexity; high confidentiality impact). The issue is fixed in version 1.15.0.1; sites on affected versions should update now. Disclosed January 2020.

Vulnerability Overview

The Import and export users and customers plugin for WordPress is vulnerable to Sensitive Data Exposure in version 1.15 via the export_users_csv function. This can allow authenticated attackers to export user information even if they do not have account creation privileges. The function was introduced in this version and fixed in subsequent versions.

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 confidentiality.

CWE-269: Improper Privilege Management

Reaching this weakness in Import and export users and customers 1.15 takes a caller who can reach the endpoint. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Import and export users and customers the fix is 1.15.0.1: builds 1.15 are affected, anything from 1.15.0.1 onward is not.

Remediation

Update to version 1.15.0.1, 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: Import and export users and customers 1.15.0.1 closes this, and updating the plugin is the step that ends it.
