Technical details
The plugin's REST endpoint for updating options lacks authorization checks, CSRF protection, and validation to ensure modified options belong to the plugin itself. An unauthenticated attacker can send a crafted request to modify arbitrary WordPress blog options, including those that control user roles and accounts. This allows account creation with administrative privileges and complete site takeover.
