What is CVE-2025-52475?

The Chamilo Learning Management System, prior to version 1.11.30, is vulnerable to a reflected cross-site scripting (XSS) attack in the admin/user_list.php endpoint. This vulnerability arises because the 'keyword_inactive' parameter is inadequately sanitized, enabling attackers to execute malicious JavaScript code by crafting a specially designed URL. Users are recommended to upgrade to version 1.11.30 to mitigate this risk.
