CVE-2024-4149Public exploitNetwork attack vector

Stored XSS via unsanitized color setting

Published Jun 13, 2024 · Updated Mar 26, 2025

Stored XSS in Premio Chaty before 3.2.3 allows remote authenticated users with administrator access to execute script in visitors' browsers. The cht_social_Phone[contact_form_title_bg_color] setting accepts a crafted HTML payload without sanitization or output escaping and stores it for later rendering. Administrator access is required, and script execution occurs when another user loads the affected widget, permitting browser-context data access or page modification.
