• EPSS: 6.7% probability of exploitation in the next 30 days
• Public exploit or detection template: yes

• Weakness: CWE-434

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.

Affected products

• Frontend File Manager Plugin: before 4.0 — fixed in 4.0
• Najeebmedia Post Front-End Form: before 1.1 — fixed in 1.1

How to fix

Upgrade to a fixed version: Frontend File Manager Plugin 4.0; Najeebmedia Post Front-End Form 1.1. Check the vendor advisory for mitigations.
