CVE-2022-4617Public exploitNetwork attack vector

Script execution via unsanitized language namespace

Published Dec 21, 2022 · Updated Apr 14, 2025

Reflected XSS in Microweber before 1.3.2 allows remote authenticated users to execute script through the language import settings page. The language_import.php view inserts the namespaceMD5 POST value into a JavaScript selector without sanitization; the patch applies xss_clean before interpolation. Administrative access is required, and injected script executes in the browser with access to data available to that session.
