CVE-2025-57762Public exploitNetwork attack vector

Stored XSS via unencoded document-name output

Published Aug 21, 2025 · Updated Aug 21, 2025

Stored XSS in WeGIA before 3.4.7 allows remote attackers to run scripts in users' browsers through a crafted nome value. dependente_docdependente.php stores the POST nome value in funcionario_docdependentes and returns it without output encoding, while profile_dependente.php renders the stored value directly inside an option element. The POST endpoint requires no prior privileges, but exploitation requires a user to open the affected page; successful execution can read or alter data available to that browser session.
