Shopire <= 1.0.57 - Missing Authorization to Authenticated (Subscriber+) Limited Plugin Install

The Shopire theme for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the shopire_admin_install_plugin() function in all versions up to, and including, 1.0.57. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install the 'fable-extra' plugin.
