Arbitrary file upload in Codedropz Drag And Drop Multiple File Upload - Contact Form 7

CVE-2023-5822

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.
