Advisory
Source description from Wordfence Intelligence, credited to WPScanTeam.
The Import all XML, CSV & TXT into WordPress plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the disable_main_mode function in versions up to, and including, 6.4.1. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to delete arbitrary site options.
