Craft CMS 5.0.0 before 5.11.0 RCE via Twig Sandbox Behavior Injection
Craft CMS from 5.0.0 before 5.11.0 contains a remote code execution vulnerability that allows authenticated Control Panel users to escape the Twig sandbox by passing uncleansed criteria to getNext, getPrev, or getOwners. Attackers can inject Yii "as" or "on" config keys to attach malicious event handlers that execute when the element query runs, achieving code execution as the web user.
