Overview
Affected versions of this package are vulnerable to Protection Mechanism Failure via the System\Twig\SecurityPolicy process. An attacker can read and modify arbitrary database records, execute arbitrary SQL commands, and inject PHP code to achieve remote code execution by exploiting method forwarding through Eloquent models and query builders using methods such as saveQuietly(), deleteQuietly(), increment(), decrement(), and newQuery().
