BeikeShop through 2.0.0.31 contains an insecure direct object reference vulnerability in the markAsShipped handler of RmaController that allows authenticated customers to modify other customers' returns. Attackers can submit sequential RMA ids to the account/rmas/{id}/markasshipped endpoint to overwrite courier names and tracking numbers and mark approved returns as shipped.

A security flaw has been discovered in BeikeShop up to 2.0.0.31. Impacted is the function OrderRepo::getOrderByNumber of the file beike/Repositories/OrderRepo.php of the component Guest Order Lookup. Performing a manipulation of the argument ordernumber results in enforcement of behavioral workflow. The attack can be initiated remotely. Upgrading to version 2.0.0.32 is recommended to address this issue. The patch is named 6cf25f8c15d27d1ff14a848faf645c94d20ba5f1. It is recommended to upgrade the affected component.
