CVE-2025-43804Network attack vector

Reflected XSS via unescaped search filter attribute

Published Sep 16, 2025 · Updated Sep 16, 2025

Reflected XSS in Liferay Portal and Liferay DXP Search widgets allows remote attackers to inject script through the userId parameter. The users.jsp view writes the user-derived filter value directly into a data-value attribute without HTML attribute escaping. A victim must open the crafted request; successful exploitation runs attacker-controlled script in the victim's browser context, enabling page-data access or actions under that session.
