CVE-2025-62248Network attack vector

Authenticated browser script execution via reflected parameter

Published Oct 22, 2025 · Updated Oct 22, 2025

Reflected XSS in Liferay Portal 7.4.0 through 7.4.3.132 and DXP 2024.Q1 through 2025.Q2 allows remote authenticated users to execute JavaScript. The DDM portlet reflects the _com_liferay_dynamic_data_mapping_web_portlet_DDMPortlet_definition parameter into a browser-executable response without neutralizing its value. Exploitation requires high-privileged access and a victim to open the crafted URL, enabling script execution in that victim's browser context.
