Technical details
The vulnerability exists in ElementInterface::getNext(), getPrev(), and NestedElementInterface::getOwners() methods, which accept uncleansed criteria arrays and pass them to Craft::configure(). By injecting Yii "as" or "on" config keys, an attacker can attach malicious event handlers that fire during query execution (EVENT_BEFORE_PREPARE). This bypasses the Twig sandbox when methods are called from sandboxed contexts such as system message rendering or element-select condition rules, requiring authenticated Control Panel access and enableTwigSandbox=true (default false).
Affected products
- Craft CMS 5.0.0 to 5.10.x
