CVE-2025-41026Network attack vector

Unauthenticated script execution via reflected site parameter

Published Mar 26, 2026 · Updated Mar 26, 2026

Reflected XSS in GDTaller allows remote attackers to execute JavaScript in a victim's browser through a malicious login URL. The site parameter in app_login.php is reflected into the generated page without sufficient neutralization, causing supplied script content to execute in the GDTaller origin. No authentication is required, but a victim must open the crafted URL; execution is confined to the browser context associated with the vulnerable application.
