In recent days it has been brought to my attention that there may be a possible exploit in the extraction of certain super global arrays in maincore.php. It depends on three things: the PHP version your host is using and registar globals is set to off and magic_quotes_gpc is set to off. It is strongly recommended that you update to ensure the security of your site.
Just to clarify, is has been suggested on one site that there is an issue with the two admin files panels.php and panel_editor.php and maintenance.php. There are absolutely no problems with these files. All admin files utilise the same security protocols and cannot be tampered with by anyone without admin access.
Existing v6.01.4 users can download the file '6.01.5 Update for v6.01.4' and simply upload the inluded files and click upgrade under System Admin. The full sourceforge package has been updated.
