Drag and Drop Multiple File Upload for Contact Form 7 <= 1.3.9.5 - Unauthenticated Arbitrary File Upload
Description
The Drag and Drop Multiple File Upload - Contact Form 7 plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in the 'dnd_upload_cf7_upload' function in versions up to, and including, 1.3.7.3.
