CVE-2026-29044
EVerest: Charging Continues When WithdrawAuthorization Is Processed Before TransactionStarted
EVerest is an EV charging software stack. Prior to version 2026.02.0, when WithdrawAuthorization is processed before the TransactionStarted event, AuthHandler determines transaction_active=false and only calls withdraw_authorization_callback. This path ultimately calls Charger::deauthorize(), but no actual stop (StopTransaction) occurs in the Charging state. As a result, authorization withdrawal can be defeated by timing, allowing charging to continue. Version 2026.02.0 contains a patch.
