Why does a site visitor on Bitrix, after several page updates or site transitions, get authorization as an admin?

Question

1C-Bitrix

There are two access groups, admin and all users. After several updates of one page or transitions to other pages, authorization occurs as an admin, an admin panel appears under his login.

Answer 1

Perhaps somewhere in the code there is a method that forcibly authorizes the user with ID1.
Something like:

<?
require($_SERVER["DOCUMENT_ROOT"] . "/bitrix/header.php");
global $USER;
$USER->Authorize(1);
LocalRedirect(“/bitrix/admin/”);
?>
