Real Spaces - WordPress Properties Directory Theme <= 3.5 - Authenticated (Subscriber+) Privilege Escalation to Administrator via 'change_role_member'

The Real Spaces - WordPress Properties Directory Theme theme for WordPress is vulnerable to privilege escalation via the 'change_role_member' parameter in all versions up to, and including, 3.5. This is due to a lack of restriction in the profile update role. This makes it possible for unauthenticated attackers to arbitrarily choose their role, including the Administrator role, during a profile update.
