EVerest: Charging Continues When WithdrawAuthorization Is Processed Before TransactionStarted

State: Published
Severity: 5.0 Medium

Description

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.
