Choose User Role at Registration for WooCommerce < 1.3.3 - Unauthenticated Privilege Escalation via Registration Role Request

Description

The plugin does not validate the role requested at registration against the roles an administrator chose to offer, allowing unauthenticated users to request any role, including administrator, and to be granted it once the request is approved. Exploitation requires the plugin's role selection feature and public account registration to both be enabled.
