At a glance

CVE-2023-3709 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Royal Addons for Elementor WordPress plugin, affecting versions <= 1.3.70. 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 1.3.71; sites on affected versions should update now. Disclosed July 2023, reported by Ulyses Saicha.

Vulnerability Overview

The Royal Elementor Addons plugin for WordPress is vulnerable to unauthenticated API key disclosure in versions up to, and including, 1.3.70 due to the plugin adding the API key to the source code of any page running the MailChimp block. This makes it possible for unauthenticated attackers to obtain a site's MailChimp API key. We recommend resetting any MailChimp API keys if running a vulnerable version of this plugin with the MailChimp block enabled as the API key may have been compromised.

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-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Royal Addons for Elementor <= 1.3.70 takes no account at all. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Royal Addons for Elementor the fix is 1.3.71: builds <= 1.3.70 are affected, anything from 1.3.71 onward is not.

Remediation

Update to version 1.3.71, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Royal Addons for Elementor 1.3.71 closes this, and updating the plugin is the step that ends it.
