yudao-cloud through 2026.09 contains an insecure direct object reference vulnerability in the mall trade module that allows authenticated members to read other members' after-sale operation logs by supplying arbitrary afterSaleId values. Attackers can enumerate sequential after-sale IDs against GET /app-api/trade/after-sale-log/list to expose refund amounts, status transitions and timestamps belonging to other members.
