CRMEB 5.6.1 through 6.0.0 contains an insecure direct object reference vulnerability that allows authenticated storefront users to read and claim other users' orders via the gift-order API. Attackers can enumerate sequential order IDs in gift_detail to harvest buyer identities and the gift_key, then call receive_gift to redirect paid goods to their address.
