What is CVE-2026-67347?

Vendure, up to version 3.7.1, is susceptible to a cross-channel authorization bypass in the stock-location.service.ts and asset.service.ts update methods. This vulnerability allows administrators with channel-scoped permissions to manipulate data from other tenants by supplying global IDs of StockLocation or Asset entities from different channels, thereby compromising data integrity due to insufficient channel isolation checks. The issue has been documented and patched in subsequent commits to ensure secure asset and inventory management across different workflow channels.
