## Overview

Craft CMS from 5.10.2 before 5.10.14 contains a Twig sandbox bypass that allows non-admin users to invoke PHP callables through the "has some" and "has every" operators. Users with the System Messages permission can supply two-argument callables such as passthru or system in sandboxed templates to execute code as the web user.
