What the vulnerability does
01Description
The BM Content Builder plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the ux_cb_tools_import_item_ajax AJAX action in all versions up to, and including, 3.16.2.1. This makes it possible for authenticated attackers, with Subscriber-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.
Explanation of Vulnerability in Simple Terms
02Summary
BM Content Builder versions 3.16.2.1 and earlier lack proper authorization checks, allowing authenticated users with low privileges to read, modify, or delete sensitive data and functionality. An attacker with a basic user account can perform actions restricted to administrators without additional interaction. This affects all data and operations within the builder component.
What an attacker can do
03Attacker Capabilities
Read, modify, or delete any data and functionality in the builder with a low-privilege user account.
Potential impact on your site
04Site Impact
Any registered user can access and alter content, settings, and data meant only for administrators.
