Publicly Published	July 16, 2016
Last Updated	January 7, 2023

Description

The Frontend File Manager (versions < 4.0), N-Media Post Front-end Form (versions < 1.1) plugins for WordPress are vulnerable to arbitrary file uploads due to missing file type validation via the `nm_filemanager_upload_file` and `nm_postfront_upload_file` AJAX actions. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected sites server which may make remote code execution possible.

Wordfence blocked 561,866 attacks targeting this vulnerability in the past 24 hours.
