CVE-2026-79419Network attack vector

Victim-browser script execution via unsanitized mensagem

Published Sep 4, 2026 · Updated Sep 4, 2026

Reflected XSS in EMX Tecnologia Gestao X Business Suite 8.4 and earlier allows remote attackers to execute JavaScript in a victim's browser. The /Configuracao/Imagens.aspx endpoint reflects the mensagem parameter into a response without sufficient validation or sanitization. No authentication is required to supply the payload, but a victim must open the crafted request before the script runs in the application's browser context.
