      "value": "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."

      "value": "EVerest es una pila de software de carga de veh\u00edculos el\u00e9ctricos. En versiones hasta la 2025.12.1 inclusive, es posible omitir la verificaci\u00f3n del estado de la secuencia, incluyendo la autenticaci\u00f3n, y enviar solicitudes que transicionan a estados prohibidos en relaci\u00f3n con el actual, actualizando as\u00ed el contexto actual con datos ileg\u00edtimos. Gracias al dise\u00f1o modular de EVerest, la autorizaci\u00f3n se gestiona en un m\u00f3dulo separado y la m\u00e1quina de estados interna del cargador EVSEManager no puede transicionar fuera del estado \u0027WaitingForAuthentication\u0027 a trav\u00e9s de la comunicaci\u00f3n ISO 15118-2. Desde este estado, sin embargo, fue posible a trav\u00e9s de mensajes ISO 15118-2 que se publican en el servidor MQTT enga\u00f1arlo para que se prepare para cargar, e incluso para que se prepare para enviar corriente. El requisito final para enviar corriente al veh\u00edculo el\u00e9ctrico fue el cierre de los contactores, lo cual no parece ser posible sin salir del estado \u0027WaitingForAuthentication\u0027 y aprovechar los mensajes ISO 15118-2. A la fecha de publicaci\u00f3n, no hay versiones corregidas disponibles."
