What the vulnerability does

01Description

EVerest is an EV charging software stack. Versions prior to 2026.02.0 have an out-of-bounds access (std::vector) that leads to possible remote crash/memory corruption. This is because the CSMS sends UpdateAllowedEnergyTransferModes over the network. Version 2026.2.0 contains a patch.
