CVE-2026-76634Public exploitNetwork attack vector

Authenticated record disclosure via id_pessoa override

Published Aug 20, 2026 · Updated Aug 20, 2026

Authorization bypass in WeGIA before 3.9.2 allows remote authenticated users to read arbitrary employee records via id_pessoa injection. In html/funcionario/profile_funcionario.php, extract($_REQUEST) runs after $id_pessoa is loaded from $_SESSION and overwrites that trusted identifier with attacker-supplied request data before the profile queries execute. Any valid account can iterate id_pessoa values to enumerate employee profiles and expose PII and the adm_configurado administrative flag; the flaw grants read access only.
