CVE-2025-54076Public exploitNetwork attack vector

Browser script execution via unescaped msg_e reflection

Published Jul 18, 2025 · Updated Jul 22, 2025

Reflected XSS in WeGIA before 3.4.6 allows remote attackers to run script in a victim's browser through a crafted msg_e URL. The pre_cadastro_atendido.php endpoint reflects msg_e into its HTTP response without validation or output neutralization. Exploitation requires a victim to open the crafted URL, after which script runs in the WeGIA origin and can access session-exposed data.
