Insert or Embed Articulate Content into WordPress <= 4.3000000025 is vulnerable to Arbitrary File Upload vulnerability

The Insert or Embed Articulate Content into WordPress plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to, and including, 4.3000000025. This makes it possible for authenticated attackers, with Editor-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
