What the vulnerability does
01Description
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 hubwoo_save_updates() 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.

A logged-in user with low privileges can perform actions they should not be permitted to do, including reading sensitive data, modifying site content, or disrupting service.
