CVE-2026-40702: EVoke Systems EVoke CSMS missing authentication in WebSocket endpoints

CVE-2026-40702 · Severity: critical · CVSS 9.4 · Published 2026-06-25

EVoke Systems Charging Station Management System (CSMS), a platform used to manage electric vehicle charging infrastructure, contains a critical security flaw in its communication endpoints. Attackers can exploit this to impersonate legitimate charging stations, allowing them to intercept sensitive data or perform unauthorized administrative actions. This could lead to a total compromise of the charging network, potentially resulting in service outages or unauthorized access to customer and operational information.

Technical details

The vulnerability is classified as a Missing Authentication for Critical Function (CWE-306) within the WebSocket endpoints of the EVoke CSMS. The system fails to properly validate the identity of connecting Electric Vehicle Supply Equipment (EVSE) when using legacy OCPP security profiles (0 or 1). A remote, unauthenticated attacker can exploit this by spoofing a charger identifier to establish a connection, enabling privilege escalation, data theft, or unauthorized control over charging operations. EVoke is addressing this by migrating to OCPP Security Profiles 2 (TLS with basic auth) or 3 (mTLS) and implementing server-side mitigations like charger ID allow-listing and session limiting for legacy devices.
