CVE-2026-32712Public exploitNetwork attack vector

Cross-user script execution via unescaped customer names

Published Apr 7, 2026 · Updated Apr 7, 2026

Stored XSS in Open Source Point of Sale before 3.4.3 allows remote authenticated users to execute JavaScript in report viewers' browsers. The Daily Sales table helper disables HTML escaping for customer_name, so stored first_name or last_name input is rendered as raw HTML. Customer-management permission and a victim opening /sales/manage are required; the script can read page content and CSRF tokens and act as the victim.
