## Description

The ThemeREX Addons plugin before 2020-03-09 for WordPress lacks access control on the /trx_addons/v2/get/sc_layout REST API endpoint, allowing for PHP functions to be executed by any users, because includes/plugin.rest-api.php calls trx_addons_rest_get_sc_layout with an unsafe sc parameter.

## What to do
