Stored XSS via unescaped user full name

Published Sep 21, 2022 · Updated Jul 9, 2026

The Site Memberships Web user_info_panel.jsp prints curUser.getFullName() inside a heading without HTML escaping. An attacker must set the crafted name and induce an administrator to view the membership page, which executes the script in that viewer's browser; affected Liferay DXP releases span 7.0 before fix pack 102, 7.1 before fix pack 26, 7.2 before fix pack 15, and 7.3 before service pack 3.
