Technical description

The DHVC Form plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 2.4.7. This is due to the plugin allowing a user to supply the 'role' field when registering. This makes it possible for unauthenticated attackers to register as an administrator on sites.
