At a glance

CVE-2026-107629 is a medium-severity Improper Neutralization of Input During Web Page Generation vulnerability in the Greenshift WordPress plugin, affecting versions <= 13.2.1. It carries a CVSS score of 5.4 (reachable over the network). Exploitation requires no authentication. The issue is fixed in version 13.2.2; sites on affected versions should update now. Disclosed October 2026, reported by UKO.

Vulnerability Overview

The Greenshift – animation and page builder blocks plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 13.2.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the affected post page to include an Advanced HTML Element block with Split Text animation enabled wrapping a Latest Comments block that displays comment excerpts, as this configuration causes splittext.js to be enqueued and to process the comment content container.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user.

CWE-79: Improper Neutralization of Input During Web Page Generation

Greenshift <= 13.2.1 carries this weakness at comment, and reaching it 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 Greenshift the fix is 13.2.2: builds <= 13.2.1 are affected, anything from 13.2.2 onward is not.

Remediation

Update to version 13.2.2, 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: Greenshift 13.2.2 closes this, and updating the plugin is the step that ends it.
