CVE-2023-5235

HIGH

8.8

CVSS v3

NVD

Description

The Ovic Responsive WPBakery WordPress plugin before 1.2.9 does not limit which options can be updated via some of its AJAX actions, which may allow attackers with a subscriber+ account to update blog options, such as 'users_can_register' and 'default_role'. It also unserializes user input in the process, which may lead to Object Injection attacks.
