Description

NexoPOS through 6.2.4 contains a missing authentication vulnerability that allows unauthenticated attackers to read accounting transaction records via GET /api/fields/{resource}/{identifier}. Attackers can request transaction field classes like ns.entity-transaction with sequential ids to retrieve names, values, account ids, and descriptions without nexopos.read.transactions permission.
