## Description

The Advanced Form Integration plugin for WordPress is vulnerable to Privilege Escalation via the FluentAffiliate Create Affiliate action in all versions up to, and including, 2.11.3, due to the role check relying on an incomplete name-based blocklist (administrator, editor, author, shop_manager) instead of the role's capabilities. This makes it possible for unauthenticated attackers to create a WordPress account with the contributor role or any privileged custom role registered on the site, including custom roles that carry administrative capabilities. Exploitation requires a public form connected to this action with the role mapped from a submitted form field.
