Description

The WholesaleX – B2B & Wholesale Plugin for WooCommerce with Wholesale Prices plugin for WordPress is vulnerable to Limited Privilege Escalation in all versions up to, and including, 3.0.8 via the 'process_registration' due to missing validation on the 'wholesalex_registration_role' parameter. This makes it possible for unauthenticated attackers to register as any existing WholesaleX role. The vulnerability was partially patched in version 2.3.8.
