Official description

CyberPanel before 3.0.0 contains a hard-coded JWT secret vulnerability in the WebTerminal FastAPI SSH service that allows unauthenticated remote attackers to forge valid authentication tokens and obtain an interactive root shell via WebSocket on port 8888. Attackers can craft a forged JWT signed with the hardcoded secret value, specifying ssh_user=root, to authenticate to the terminal service without any valid credentials and receive a root shell.
