Official Description

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.

Technical Analysis

CVE-2026-27028 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
