At a glance

CVE-2021-4445 is a medium-severity Missing Authorization vulnerability in the Premium Addons for Elementor WordPress plugin, affecting versions <= 4.5.1. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 4.5.2; sites on affected versions should update now. Disclosed August 2021, reported by WPScanTeam.

Vulnerability Overview

The Premium Addons for Elementor plugin for WordPress is vulnerable to Arbitrary Option Updates in versions up to, and including, 4.5.1. This is due to missing capability and nonce checks in the pa_dismiss_admin_notice AJAX action. This makes it possible for authenticated subscriber+ attackers to change arbitrary options with a restricted value of 1 on vulnerable WordPress sites.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed.

CWE-862: Missing Authorization

Reaching this weakness in Premium Addons for Elementor <= 4.5.1 takes an account at Subscriber level or above. 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 Premium Addons for Elementor the fix is 4.5.2: builds <= 4.5.1 are affected, anything from 4.5.2 onward is not.

Remediation

Update to version 4.5.2, 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: Premium Addons for Elementor 4.5.2 closes this, and updating the plugin is the step that ends it.
