At a glance

CVE-2024-4566 is a high-severity Missing Authorization vulnerability in the ShopLentor WordPress plugin, affecting versions <= 2.8.8. It carries a CVSS score of 7.1 (reachable over the network; low attack complexity; high availability impact). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 2.8.9; sites on affected versions should update now. Disclosed May 2024, reported by TheGreatLol.

Vulnerability Overview

The ShopLentor plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the ajax_dismiss function in all versions up to, and including, 2.8.8. This makes it possible for authenticated attackers, with contributor-level access and above, to set arbitrary WordPress options to "true". NOTE: This vulnerability can be exploited by attackers with subscriber- or customer-level access and above if (1) the WooCommerce plugin is deactivated or (2) access to the default WordPress admin dashboard is explicitly enabled for authenticated users.

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 availability.

CWE-862: Missing Authorization

ShopLentor <= 2.8.8 carries this weakness at true, 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 ShopLentor the fix is 2.8.9: builds <= 2.8.8 are affected, anything from 2.8.9 onward is not.

Remediation

Update to version 2.8.9, 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: ShopLentor 2.8.9 closes this, and updating the plugin is the step that ends it.
