Authentication Bypass in EVerest EVSEManager via ISO 15118-2 Messages

Publication date: 2026-01-26

Assigner: GitHub, Inc.

Description
EVerest is an EV charging software stack. In versions up to and including 2025.12.1, it is possible to bypass the sequence state verification including authentication, and send requests that transition to forbidden states relative to the current one, thereby updating the current context with illegitimate data.cThanks to the modular design of EVerest, authorization is handled in a separate module and EVSEManager Charger internal state machine cannot transition out of the `WaitingForAuthentication` state through ISO 15118-2 communication. From this state, it was however possible through ISO 15118-2 messages which are published to the MQTT server to trick it into preparing to charge, and even to prepare to send current. The final requirement to actually send current to the EV was the closure of the contactors, which does not appear to be possible without leaving the `WaitingForAuthentication` state and leveraging ISO 15118-2 messages. As of time of publication, no fixed versions are available.

Executive Summary

This vulnerability in the EVerest EV charging software stack allows an attacker to bypass sequence state verification and authentication. By sending ISO 15118-2 messages published to the MQTT server, an attacker can trick the internal state machine of the EVSEManager Charger into transitioning to forbidden states, such as preparing to charge or preparing to send current, even while still in the 'WaitingForAuthentication' state. However, the final step of actually sending current requires leaving this state, which is not possible through this vulnerability.

Impact Analysis

The vulnerability can allow unauthorized manipulation of the EV charging process by bypassing authentication and state verification. This could lead to the system preparing to charge or send current illegitimately, potentially causing operational disruptions or misuse of the charging infrastructure. However, the attacker cannot actually send current without proper state transitions, limiting the impact to preparation stages.

Mitigation Strategies

As of the time of publication, no fixed versions are available. Immediate mitigation steps are not specified in the provided information.
