What is CVE-2026-105261?

The PublishPress Future plugin for WordPress, prior to version 4.10.6, lacks proper enforcement of a safe HTML-element allowlist for shortcode attributes. As a result, this allows users with the Contributor role and above to inject malicious JavaScript code. This code executes in the browser session of any admin or higher-privileged user who views the affected content, potentially leading to unauthorized access and manipulation of site data.
