"is_projectPath" parameter:
includes/InstantSite/inc.is_root.php

"GLOBALS[thCMS_root]" parameter:

2) Input passed to the "thCMS_root" parameter in includes/inc.thcms_admin_dirtree.php is not properly verified before being used to read files. This can be exploited to read arbitrary files from local resources.

3) Input passed to the "fm_includes_special" parameter in includes/file_manager/special.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local or external resources.
