WeGIA before 3.9.2 contains an insecure direct object reference vulnerability in the employee profile page that allows authenticated attackers to access arbitrary employee records by injecting an id_pessoa parameter through a request extraction function that overwrites the session-derived identifier. Attackers can enumerate all user identifiers to retrieve full profile data for any employee account, including name, CPF, address, contact details, and administrative flags.
