CVE-2024-11204Network attack vector

Script execution via unescaped list-column URL

Published Dec 6, 2024 · Updated Apr 8, 2026

Reflected XSS in Ultimate Member Group Ltd ForumWP 2.1.2 and earlier allows remote attackers to run scripts via a crafted url parameter. The admin list-column renderer passes the request's url value through add_query_arg() and remove_query_arg() and prints the resulting URL without escaping it. Execution requires a user to follow the crafted link, after which the script runs in that user's browser context.
