Missing authorization in JoomShaper Helix Ultimate 1.0 through 2.2.6 allows remote attackers to delete server files through AJAX. The frontend com_ajax dispatcher invokes Media::deleteMedia after accepting an anonymous session token, without checking authorization. Unauthenticated network access is sufficient to remove writable files or directories and interrupt the Joomla site.
