CVE-2026-26288
CriticalSummary
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.
Risk Assessment
Lack of authentication can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend.
Recommendation
It is recommended to implement proper authentication mechanisms for WebSocket endpoints to prevent unauthorized access and data manipulation.
Original NVD description (English source)
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.
