CVE-2025-54816

EVMAPA Missing Authentication for Critical Function

Published Jan 22, 2026 CVSS 3.1 · 9.4 Critical EPSS < 1% KEV · Not listed
Description
This vulnerability occurs when a WebSocket endpoint does not enforce
proper authentication mechanisms, allowing unauthorized users to
establish connections. As a result, attackers can exploit this weakness
to gain unauthorized access to sensitive data or perform unauthorized
actions. Given that no authentication is required, this can lead to
privilege escalation and potentially compromise the security of the
entire system.

Remediation

Vendor Workaround

EVMAPA informed CISA some of their charging stations do not allow changes to the authorization key using the Open Charge Point Protocol (OCPP). Currently, charge point operators have the option to connect stations using WebSocket Secure (WSS), and EVMAPA connects stations they supply via their own VPN. For OCPP 2.x and newer stations, EVMAPA plans to implement BASIC authorization control.
