Authenticated script execution via unescaped productTypeName reflection
Published Sep 24, 2025 · Updated Sep 24, 2025
Reflected XSS in affected Liferay Portal and DXP releases allows remote authenticated users to execute JavaScript via productTypeName. The CPDefinitionsPortlet response places the productTypeName request parameter into page output without neutralizing executable markup, so the browser interprets the reflected value as script. Exploitation requires access to the Commerce Product Definitions portlet and a browser loading the crafted request; the script runs in the page's origin and can read or alter data available to that browsing session.
