Cross-order status modification via missing ownership validation
Published Aug 3, 2026 · Updated Aug 3, 2026
Authorization bypass in the Dokan WordPress plugin before 5.0.9 allows remote authenticated users to change any marketplace order's status. The orders/bulk-actions REST endpoint accepts attacker-selected order identifiers without verifying that each order belongs to the requesting vendor. A Dokan vendor account is required; the flaw permits cross-vendor and store-customer order-status changes without reported data disclosure.
