Advisory
Source description from Wordfence Intelligence, credited to Nguyen Anh Tien.
The WPvivid Backup Plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to a missing capability check on the 'start_staging' and 'get_staging_progress' functions in versions up to, and including, 0.9.90. This makes it possible for authenticated attackers to create new staging sites and fresh WordPress installations on the server that use arbitrary database connections under the attacker's control. This can allow full site takeover via an attacker who grants themselves administrator privileges on the new database, at which point the site they control shares a file system with the victim site.
