The ThemeGrill Demo Importer plugin for WordPress is vulnerable to authentication bypass due to a missing capability check on the reset_wizard_actions function in versions 1.3.4 through 1.6.1. This makes it possible for authenticated attackers to reset the WordPress database. After which, if there is a user named 'admin', the attacker will become automatically logged in as an administrator.

themegrill-demo-importer before 1.6.3 allows CSRF, as demonstrated by wiping the database.

themegrill-demo-importer before 1.6.2 does not require authentication for wiping the database, because of a reset_wizard_actions hook.
