Description
The Tatsu WordPress plugin before 3.3.13 add_custom_font action can be used without prior authentication to upload a rogue zip file which is uncompressed under the WordPress's upload directory. By adding a PHP shell with a filename starting with a dot ".", this can bypass extension control implemented in the plugin. Moreover, there is a race condition in the zip extraction process which makes the shell file live long enough on the filesystem to be callable by an attacker.
Wordfence blocked 5,013 attacks targeting this vulnerability in the past 24 hours.
