HashThemes Demo Importer < 1.1.2 - Improper Access Control to Blog Reset

Description

The plugin does not have capability checks in some of its AJAX action, relying on CSRF nonces for this, which are displayed for any authenticated users. As a result, a user with a role as low as subscriber could use the hdi_install_demo AJAX action to reset the entire blog (including the tables in the database except wp_options, wp_users, and wp_usermeta)
