Advisory

Source description from Wordfence Intelligence, credited to Abdi Pranata.

Multiple WPOnlineSupport plugins for WordPress are vulnerable to unauthorized modification of data due to a missing capability check on the wpos_anylc_admin_init_process() function hooked via admin_init in various versions. This makes it possible for unauthenticated attackers to dismiss a license notice.
