CVE-2016-15042 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.

EPSS estimates a 5.51% chance of exploitation in the next 30 days.
