The Malcolm kiosk Flask application exposes a POST /script_call/<script> endpoint with zero authentication and wildcard CORS (CORS(app)). An attacker can force the operator's browser to execute arbitrary management commands via CSRF, including control.py --wipe which permanently deletes all captured network traffic and forensic logs, or control.py --stop which blinds the security monitoring.
