CVE-2024-11582Network attack vector

Unauthenticated stored XSS via unescaped subscriber IP attribute

Published Feb 19, 2025 · Updated Apr 8, 2026

Stored XSS in weDevs Subscribe2 10.43 and earlier allows remote attackers to inject scripts through the public form's ip parameter. S2_List_Table::column_email inserts the stored subscriber IP directly into an HTML title attribute without output escaping. No authentication is required to plant the value; execution occurs when an administrator views the subscriber list, exposing that browser session to script actions.
