CVE-2026-111032: Welcart e-Commerce authorization bypass in SKU management

CVE-2026-111032 · Severity: info · Published 2026-10-28

Welcart e-Commerce is a WordPress plugin that manages online shopping carts and product catalogs. An authenticated WordPress author or higher-level user can bypass product access controls to view, modify, and delete pricing, cost data, and inventory information for products they do not own. This exposure of confidential cost data and stock levels could lead to competitive intelligence leaks or inventory manipulation by unauthorized staff.

Technical details

The plugin fails to bind capability checks to specific products during SKU change processing, allowing any authenticated Author+ user to invoke the item_sku_ajax endpoint on arbitrary products. An attacker with Author-level access or higher can read and modify confidential fields (prices, cost prices, stock levels) across all products via AJAX, regardless of product ownership. The vulnerability requires authentication but permits full CRUD operations on SKU data outside the attacker's authorization scope.
