| Package | Affected versions | Patched versions |
|---|---|---|
| frontend file manager | < 4.0 | 4.0 |
| post front-end form | < 1.1 | 1.1 |
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.
