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 6.4.12; sites on affected versions should update now. Disclosed May 2026, reported by theviper17y.

Vulnerability Overview

The Plus Addons for Elementor plugin for WordPress was vulnerable to Authenticated (Contributor+) Stored Cross-Site Scripting via the Button widget's `custom_attributes` setting in versions up to and including 6.4.11. The `render` function in `modules/widgets/tp_button.php` passed the raw `custom_attributes` string through `tp_senitize_js_input()`. This filter is bypassable. The issue is patched in version 6.4.12.

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')

The Plus Addons for Elementor <= 6.4.11 carries this weakness at tp_senitize_js_input(), 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 The Plus Addons for Elementor the fix is 6.4.12: builds <= 6.4.11 are affected, anything from 6.4.12 onward is not.

Remediation

Update to version 6.4.12, 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: The Plus Addons for Elementor 6.4.12 closes this, and updating the plugin is the step that ends it.
