CVE-2026-120520: Greenshift animation and page builder blocks sensitive information exposure

CVE-2026-120520 · Severity: medium · CVSS 5.3 · Published 2026-11-07

The Greenshift plugin adds custom animation and page building capabilities to WordPress sites. If a site administrator configures an image block with a template placeholder, attackers can craft a malicious link that tricks logged-in users into leaking their WordPress session cookies. This could allow an attacker to hijack user accounts and gain unauthorized access to the WordPress site.

Technical details

The vulnerability exists in the plugin's template placeholder processing, where {{GET:}} and {{COOKIE:}} placeholders are not properly sanitized when building image src attributes. An unauthenticated attacker can inject a nested {{COOKIE:}} placeholder through a GET parameter, causing the victim's browser to send sensitive HttpOnly cookies (wordpress_logged_in_*) to an attacker-controlled host. Exploitation requires both that the site publisher has configured a public GreenShift Element image block with a {{GET:}} placeholder in its src attribute and that a logged-in user clicks the attacker's crafted link.
