LowCVSS 3.8Exploitation Probability (EPSS)
Low risk9th percentile - higher than 9% of all known CVEs
Summary
The Welcart e-Commerce WordPress plugin before 2.12.6 does not properly verify authorization against the targeted product before processing SKU changes, because its capability check is not tied to the product being edited. This allows any authenticated user with Author-level access or higher to read, modify, create, delete and re-order the SKU data (including prices, confidential cost prices and stock levels) of any product, including those belonging to other users.
Risk Assessment
An Author-level user can modify other users' product data, including confidential cost prices and stock levels, potentially leading to financial loss and data leakage.
Recommendation
Update the Welcart e-Commerce plugin to version 2.12.6 or later.
