Official description
The Custom Fields Account Registration For Woocommerce WordPress plugin before 1.4 does not prevent its custom registration fields from writing to the user capabilities meta key on sites that use a non-default database table prefix, so an unauthenticated user who registers an account can be granted the administrator role when a correspondingly named field has been configured.

The underlying weakness: Improper Privilege Management
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
