Vulnerability Overview

The Checkout Mestres WP plugin for WordPress is vulnerable to authentication due to a weak password reset functionality in all versions up to, and including, 7.1.9.6. This makes it possible for unauthenticated attackers to reset the password of arbitrary users to a guessable value based on the current time.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-640: Weak Password Recovery Mechanism for Forgotten Password

Reaching this weakness in Checkout Mestres do WP for WooCommerce <= 7.1.9.6 takes a caller who can reach the endpoint. A weak password recovery mechanism means the path that lets someone back into an account without their password is easier to complete than the password itself.

An attacker takes over an account through the recovery flow without ever seeing the password, and on an administrator account that is full control of the site. For Checkout Mestres do WP for WooCommerce the fix is 7.1.9.8: builds <= 7.1.9.6 are affected, anything from 7.1.9.8 onward is not.

Remediation

Update to version 7.1.9.8, 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: Checkout Mestres do WP for WooCommerce 7.1.9.8 closes this, and updating the plugin is the step that ends it.
