CVE-2026-24731Network attack vector

Unauthenticated station impersonation via unprotected WebSocket endpoint

Published Feb 26, 2026 · Updated Feb 26, 2026

Missing authentication in Ev2Go ev2go.io allows remote attackers to impersonate charging stations through its OCPP WebSocket endpoint. The endpoint accepts a known or discovered station identifier without authenticating the connecting client, then treats the connection as the legitimate charger. Network access and a station identifier are sufficient to issue or receive OCPP commands, control charging infrastructure, and corrupt data reported to the backend.
