Stored script execution via unsanitized address fields
Published Jan 30, 2026 · Updated Jan 30, 2026
Stored XSS in Sellacious eCommerce 4.6 allows remote authenticated users to execute scripts through crafted address fields. The address-management module accepts script-bearing name, company, post-office-box, address, and landmark values by POST, stores the values, and renders the data without effective neutralization. A registered low-privilege account is required; execution in customer or administrative browsers can expose session data and alter rendered content.
