CVE-2026-22521Network attack vector

Contributor-level PHP execution via local file inclusion

Published Jan 8, 2026 · Updated Jan 8, 2026

Local file inclusion in G5Theme Handmade Framework 3.9 and earlier allows remote authenticated users to execute attacker-controlled PHP. Public sources do not identify the vulnerable function or request parameter; they establish only that an attacker-controlled filename reaches a PHP include operation. Contributor-level WordPress access is required, and code execution depends on first placing PHP code in a server-accessible file that can be included.
