CVE-2025-43769Network attack vector

Stored script execution via unescaped portlet title

Published Aug 23, 2025 · Updated Aug 23, 2025

Stored XSS in the Components portlet in Liferay Portal and DXP allows remote authenticated users to execute script in another user's browser. The Components tab's portlets.jspf template writes a portlet title directly into HTML; the patch applies HtmlUtil.escape before rendering it. Exploitation requires high privileges to store a crafted title and active interaction by another user who opens the affected tab, exposing that user's browser-session data and page actions.
