Jupiter X Core < 4.6.6 - Unauthenticated Arbitrary File Upload

Description

The Jupiter X Core plugin for WordPress is vulnerable to arbitrary file uploads due to a mishandled file type validation in the 'validate' function in all versions up to, and including, 4.6.5. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
