Melapress Role Editor <= 1.1.1 - Improper Authorization to Authenticated (Subscriber+) Privilege Escalation via Secondary Role Assignment

The Melapress Role Editor plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.1.1. This is due to a misconfigured capability check on the 'save_secondary_roles_field' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to assign themselves additional roles including Administrator.
