Description
NexoPOS through 6.3.0 contains a missing authorization vulnerability that allows authenticated cashiers to manipulate other cashiers' register sessions because CashRegistersService never compares used_by with the user. Attackers holding the default nexopos.use.registers permission can submit closing, cash-in, or cash-out actions to POST /api/cash-registers/{action}/{register} to force-close sessions or alter balances.
