CVE-2025-63589
A reflected XSS vulnerability exists in CMSimple_XH 1.8's index.php router when attacker-controlled path segments are not sanitized or encoded before being inserted into the generated HTML (navigation links, breadcrumbs, search form action, footer links). An attacker-controlled string placed in the URL path is reflected into multiple HTML elements, allowing execution of arbitrary JavaScript in victims' browsers visiting a crafted URL.
