CVE-2024-44778Public exploitNetwork attack vector

Browser script execution via reflected parent parameter

Published Aug 29, 2024 · Updated Jul 5, 2026

Reflected XSS in Vtiger CRM 7.4.0 allows remote attackers to execute JavaScript in a user's browser through a crafted URL. The index.php response reflects the parent query value into an executable browser context without neutralizing script syntax. No authentication is required, but a user must open the crafted link; the published CISA assessment limits impact to browser-context integrity.
