Advisory
Source description from Wordfence Intelligence.
The UpdraftPlus plugin for WordPress is vulnerable to Privilege Escalation due to missing authorization on the 'updraft_central_ajax_handler' function in versions from 1.22.14 to 1.23.2 inclusive, and 2.22.14 to 2.23.2 of the premium version. This allows authenticated attackers, with subscriber-level permissions or above, to update the plugin's settings in such a way that can allow them to perform administrator-level actions on some sites.
