[ Description ]Official description
ServiceNext contains an insecure direct object reference (IDOR) in the /api/Usuario/GetUsuarios endpoint, which accepts a user-controlled numeric ID in the request body without verifying that the authenticated token belongs to the requested account (CWE-639). Any authenticated user can iterate the ID parameter to retrieve the full profile record of every other user, including passwords stored in cleartext (CWE-256), enabling account takeover and credential-stuffing attacks.
