Overview

Affected versions of this package are vulnerable to Remote Code Execution (RCE) in helper method dispatch, where it uses Kernel::send to call helpers without checking that they are defined within the template context first. This allows expressions such as {{system "ls"}} or {{eval "puts 1 + 1"}} to be executed.
