CVE-2025-53377Public exploitNetwork attack vector

Browser script execution via unvalidated GET parameter

Published Jul 7, 2025 · Updated Jul 8, 2025

Reflected XSS in WeGIA before 3.4.3 allows remote attackers to run scripts in a victim's browser through a crafted id_funcionario value. The cadastro_dependente_pessoa_nova.php endpoint inserts that raw GET value into an unquoted hidden-input attribute, allowing markup to break out and execute. Exploitation requires a victim to open an attacker-crafted URL; the script runs in WeGIA's origin and can read or alter data available to that victim.
