CVE-2026-27767

WebSocket endpoints lack proper authentication mechanisms, enabling 
attackers to perform unauthorized station impersonation and manipulate 
data sent to the backend. An unauthenticated attacker can connect to the
 OCPP WebSocket endpoint using a known or discovered charging station 
identifier, then issue or receive OCPP commands as a legitimate charger.
 Given that no authentication is required, this can lead to privilege 
escalation, unauthorized control of charging infrastructure, and 
corruption of charging network data reported to the backend.
