Advisory

Source description from Wordfence Intelligence, credited to Farid Narimanov.

The B2BKing — Ultimate WooCommerce B2B and Wholesale Plugin — Wholesale Prices, Bulk Order Form & More plugin for WordPress is vulnerable to unauthorized access in all versions up to 5.2.40. This is due to missing validation of the submitted registration role against the list of publicly available, published, and selectable custom roles. This makes it possible for unauthenticated attackers to assign themselves to arbitrary restricted B2B customer groups and bypass the manual account-approval workflow during self-registration.
