High (8.5). EPSS 0.8% estimated probability of exploitation activity in the next 30 days.
Control Web Panel (CWP) before webpanel_version 1.29 contains an OS command injection vulnerability in the loopback API database restore route /v1/restoredatabase/, where the restoreDBBackup() handler passes an attacker-controlled file path from the POST body into a shell command without proper escaping. An attacker able to reach the route can inject arbitrary OS commands that execute as root.
