The MWB HubSpot for WooCommerce – CRM, Abandoned Cart, Email Marketing, Marketing Automation & Analytics plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the hubwoosaveupdates() function in all versions up to, and including, 1.5.9. This makes it possible for authenticated attackers, with Contributor-level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.

The Wallet System for WooCommerce WordPress plugin before 2.8.0 does not perform any capability check, and relies on a token any authenticated user can obtain from a front-end page, before generating a report containing every customer's wallet transaction history, allowing any authenticated user, such as a subscriber, to disclose all users' names, email addresses, roles, transaction amounts, payment methods and dates.
