Browser script execution via undisclosed reflected input

Published Aug 5, 2023 · Updated Apr 28, 2026

Reflected XSS in Shipping Multiple Addresses for WooCommerce 3.8.5 and earlier allows remote attackers to execute browser script. The public CNA record and its referenced advisory do not identify the request field, endpoint, or output operation that reflects untrusted input. No account is required, but a victim must open the crafted request; the script then runs in the victim's browser context and can access or alter page data.
