Control Web Panel (CWP) before webpanel_version 1.29 contains a missing authentication vulnerability that allows attackers able to reach the loopback API service to invoke root-privileged API routes without presenting an access token. Attackers can access endpoints such as /v1/restoredatabase/, /generaluser/, /last_access/, /valid_user/, /valid_token/, and /user_panel_dashboard/ to perform unauthorized actions with root privileges.
