It carries a CVSS score of 5.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above.

Vulnerability Overview

The Premium Addons for Elementor – Powerful Elementor Templates & Widgets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'custom_svg' parameter in versions up to, and including, 4.11.70 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, 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.

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

Premium Addons for Elementor <= 4.11.70 carries this weakness at custom_svg, 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 Premium Addons for Elementor the fix is 4.11.71: builds <= 4.11.70 are affected, anything from 4.11.71 onward is not.

Remediation

Update to version 4.11.71, 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: Premium Addons for Elementor 4.11.71 closes this, and updating the plugin is the step that ends it.
