Bit integrations < 2.8.8 - Unauthenticated Server-Side Request Forgery via Form Field Upload Mapping

Description

The Bit integrations – Form Integration, Webhook, Spreadsheets, CRM, LMS & Email Automation plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 2.8.7 via the upload_attachment. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. Exploitation requires a form integration to be configured with a field mapped to a WooCommerce product image, product gallery, downloadable files, or Google Contacts attachment field, which is a default use case for these integrations.
