CVE-2026-33015

EVerest is an EV charging software stack. Prior to version 2026.02.0, even immediately after CSMS performs a RemoteStop (StopTransaction), the EVSE can return to `PrepareCharging` via the EV's BCB toggle, allowing session restart. This breaks the irreversibility of remote stop and can bypass operational/billing/safety controls. Version 2026.02.0 contains a patch.
