WP User Switch <= 1.1.0 - Authenticated (Subscriber+) Privilege Escalation

The WP User Switch plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.1.0. This is due to the plugin not properly validating a users permissions before allowing them to switch to another user. This makes it possible for unauthenticated attackers to gain access to higher privileged user accounts.
