## Affected

- Unknown Custom Fields Account Registration For Woocommerce: fixed in 1.4

## 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.
