CVE-2025-15712 · Severity: info · Published 2026-11-11

Live Composer is a page builder plugin for WordPress that allows administrators to manage website content. The plugin fails to properly sanitize staff member settings before displaying them on pages, allowing administrators to inject malicious scripts that execute in visitors' browsers. In multisite WordPress installations where administrators lack unfiltered HTML permissions, this creates an attack vector for privilege escalation or account compromise.

## Technical details

The plugin contains a Stored Cross-Site Scripting (XSS) vulnerability in its staff member settings functionality due to insufficient input sanitization and output escaping. An authenticated administrator can inject arbitrary JavaScript code into staff settings that persists in the database and executes when pages are rendered. This bypasses WordPress multisite restrictions on the unfiltered_html capability.
