Description
The PHP2Shell vulnerability (CVE-2026-109618 & CVE-2026-109619) isn't just an issue for traditional Linux web servers and WordPress blogs—it impacts your entire homelab and network hardware! Because embedded PHP powers management web GUIs and containerized apps, unauthenticated Remote Code Execution (RCE) flaws can leave your NAS, firewalls, and self-hosted services fully exposed.
In this video, we break down what PHP2Shell is, why it affects devices like QNAP, pfSense, OPNsense, Nextcloud, and older Pi-hole deployments, and the exact step-by-step action plan to find PHP services on your local network and close the security holes before attackers exploit them.
