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.
