At a glance

CVE-2026-13407 is a high-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Royal Addons for Elementor WordPress plugin, affecting versions <= 1.7.1066. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.7.1067; sites on affected versions should update now. Disclosed September 2026, reported by Brian Willows.

Vulnerability Overview

The Royal Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 1.7.1066. This is due to missing sanitization and escaping of user-supplied form_content values before they were included in the notification email body. This makes it possible for unauthenticated attackers to inject arbitrary HTML into administrator notification emails sent on form submission.

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

Reaching this weakness in Royal Addons for Elementor <= 1.7.1066 takes no account at all. 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 Royal Addons for Elementor the fix is 1.7.1067: builds <= 1.7.1066 are affected, anything from 1.7.1067 onward is not.

Remediation

Update to version 1.7.1067, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Royal Addons for Elementor 1.7.1067 closes this, and updating the plugin is the step that ends it.
