zen cart — all zen cart url with currency parameter will be redirected to home page

i just found that if any url in a zen cart store containing currency=value,then it will be redirected to zen cart website home page.For example,

http://www.abcdomain.com/xxxxxxxxxxx/xxxxxxxxx/?currency=EUR

This url will be redirected to http://www.abcdomain.com/,it’s a 302 redirect.

is this a zen cart bug?

From the code in this file:/includes/init_includes/init_currencies.php

if ($new_currency == false || isset($_GET['language'])) $new_currency = (USE_DEFAULT_LANGUAGE_CURRENCY == 'true') ? zen_currency_exists(LANGUAGE_CURRENCY) : $new_currency;
 
// Final check -- if selected currency is bad and the "default" is bad, default to the first-found currency in order of exch rate.
if ($new_currency == false) $new_currency = zen_currency_exists(DEFAULT_CURRENCY, true);
//echo '<br />NEW = ' . $new_currency . '<br />';
 
// Now apply currency update
if (
   // Has new currency been selected?
  (isset($_GET['currency'])) ||
 
  // Does language change require currency update?
  (isset($_GET['language']) && USE_DEFAULT_LANGUAGE_CURRENCY == 'true' && LANGUAGE_CURRENCY != $_SESSION['currency']  )
 
) {
  $_SESSION['currency'] = $new_currency;
  // redraw the page without the currency/language info in the URL
  if (isset($_GET['currency']) || isset($_GET['language'])) zen_redirect(zen_href_link($current_page_base, zen_get_all_get_params(array('currency','language'))));
}
?>

the zen_redirect make this happen.
