What is CVE-2026-92458?

In yshop-crm version 2.1.3, a flaw exists in the StoreProductController where the onSale handler does not enforce proper authorization checks. This vulnerability allows authenticated back-office users to alter the sale status of products by accessing the /admin-api/product/store-product/sale endpoint with sequential product IDs. Consequently, this oversight can enable attackers to unintentionally withdraw entire product catalogs from sale or re-enable products previously withdrawn, ultimately compromising the integrity of the product management system.

Affected Version(s)

yshop-crm 0 <= 2.1.3
