Vulnerability Overview

The Unlimited Elements For Elementor (Free Widgets, Addons, Templates) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘username’ parameter in all versions up to, and including, 1.5.112 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above and granted plugin setting edit permissions by an administrator, 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Unlimited Elements For Elementor <= 1.5.112 carries this weakness at username, and reaching it 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 Unlimited Elements For Elementor the fix is 1.5.113: builds <= 1.5.112 are affected, anything from 1.5.113 onward is not.

Remediation

Update to version 1.5.113, 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: Unlimited Elements For Elementor 1.5.113 closes this, and updating the plugin is the step that ends it.
