CVE-2025-5135Public exploitNetwork attack vector

Stored XSS via unencoded product fields

Published May 24, 2025 · Updated May 28, 2025

Stored XSS in Tmall Demo 20250505 allows remote authenticated users to execute scripts via crafted Product Name or Product Title input. The administrative product-editing path stores these fields and later renders their values on the Product Details Page without HTML entity encoding. An administrator must submit the payload and another user must view the affected page; the resulting script runs in that viewer's browser context.
