CVE-2024-2618 is a medium-severity Improper Neutralization of Alternate XSS Syntax vulnerability in the Ultimate Addons for Elementor WordPress plugin, affecting versions <= 1.6.26. 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.

Vulnerability Overview

The Elementor Header & Footer Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the size attribute in all versions up to, and including, 1.6.26 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor access or higher, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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-87: Improper Neutralization of Alternate XSS Syntax

The product does not neutralize or incorrectly neutralizes user-controlled input for alternate script syntax.

Remediation

Update to version 1.6.26.1, 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: Ultimate Addons for Elementor 1.6.26.1 closes this, and updating the plugin is the step that ends it.
