Charitable <= 1.7.0.12 is vulnerable to Unauthenticated Privilege Escalation Vulnerability

The Donation Forms by Charitable plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 1.7.0.12 due to insufficient restriction on the 'update_core_user' function. This makes it possible for unauthenticated attackers to specify their user role by supplying the 'role' parameter during a registration.
