At a glance

CVE-2024-37437 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Elementor Website Builder WordPress plugin, affecting versions <= 3.22.1. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 3.22.2; sites on affected versions should update now. Disclosed June 2024, reported by stealthcopter.

Vulnerability Overview

The Elementor Website Builder – More than Just a Page Builder plugin for WordPress is vulnerable to arbitrary SVG file download in all versions up to, and including, 3.22.1. This is due to the plugin not properly restricting access to files. This makes it possible for authenticated attackers, with contributor-level access and above, to download arbitrary SVG files.

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.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in Elementor Website Builder <= 3.22.1 takes an account at Contributor level or above. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Elementor Website Builder the fix is 3.22.2: builds <= 3.22.1 are affected, anything from 3.22.2 onward is not.

Remediation

Update to version 3.22.2, or a newer patched version

How does WordSec protect against this?

An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Elementor Website Builder 3.22.2 closes this, and updating the plugin is the step that ends it.
