CVE-2026-28695Public exploitNetwork attack vector

Authenticated RCE via unrestricted Twig object creation

Published Mar 4, 2026 · Updated Mar 4, 2026

Template injection in Pixel & Tonic Craft CMS allows remote authenticated users to execute commands through crafted title formats. The Twig create() function passes attacker-controlled class names and constructor arguments to Craft::createObject(), enabling Symfony Process instantiation and command execution. Exploitation requires Administrator permissions or System Messages utility access; production also requires allowAdminChanges unless System Messages is available.
