Front-End-Only-Users < 3.2.33 - Unauthenticated Arbitrary File Upload

Description

The Front End Users plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the file uploads field of the registration form in all versions up to, and including, 3.2.32. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
