Postem Ipsum <= 3.0.1 - Missing Authorization to Authenticated (Subscriber+) Privilege Escalation in postem_ipsum_generate_users

The Postem Ipsum plugin for WordPress is vulnerable to unauthorized modification of data to Privilege Escalation due to a missing capability check on the postem_ipsum_generate_users() function in all versions up to, and including, 3.0.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create arbitrary user accounts with the administrator role.
