At a glance

CVE-2023-51357 is a medium-severity Missing Authorization vulnerability in the Conversios WordPress plugin, affecting versions <= 6.5.0. 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 6.5.1; sites on affected versions should update now. Disclosed December 2023, reported by Kévin Mosbahi (Mika).

Vulnerability Overview

The Conversios.io plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the conversios-productsync/v1/cron-productsync REST API endpoint in versions up to, and including, 6.5.0. This makes it possible for unauthenticated attackers to trigger a product sync.

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 Conversios <= 6.5.0 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 Conversios the fix is 6.5.1: builds <= 6.5.0 are affected, anything from 6.5.1 onward is not.

Remediation

Update to version 6.5.1, 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: Conversios 6.5.1 closes this, and updating the plugin is the step that ends it.
