dokan pro <= 4.1.3 - Missing Authorization to Unauthenticated Sensitive Information Exposure

The Dokan Pro plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the `/dokan/v1/wholesale/register` REST API endpoint in all versions up to, and including, 4.1.3. This makes it possible for unauthenticated attackers to enumerate users and retrieve their email addresses via the REST API by providing a user ID, along with other information such as usernames, display names, user roles, and registration dates.
