The MongoDB Node.js driver does not consistently enforce its permitted-host restriction during OIDC authentication. A bearer token produced by the embedding application's own login callback may therefore be transmitted to a host outside the configured set of permitted hosts, which may result in unintended disclosure of that credential. No database account is required; the party supplying the connection configuration needs only to influence the settings the application passes to the driver.
