CVE-2025-22143Public exploitNetwork attack vector

Victim-session script execution via unencoded error message

Published Jan 8, 2025 · Updated Jan 8, 2025

Reflected XSS in WeGIA before 3.2.8 allows remote attackers to execute script in a victim's browser through a crafted msg_e URL. The listar_permissoes.php endpoint reads msg_e from the query string and places it into an HTML error alert without output encoding, so supplied markup becomes executable browser content. Exploitation requires a victim to open the crafted URL; successful script runs in that victim's WeGIA browser context and can act with the victim's accessible session.
