What the vulnerability does

01Description

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.
