Sandbox escape through template_object in smarty
Sandbox protection could be bypassed through access to an internal Smarty object that should have been blocked. Sites that rely on [Smarty Security features](https://www.smarty.net/docs/en/advanced.features.tpl) should upgrade as soon as possible. Please upgrade to 3.1.39 or higher.
