stated drag_and_drop_multiple_file_upload_-_contact_form_7 · vendor CodeDropz drag_and_drop_multiple_file_upload_-_contact_form_7

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. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. This can be exploited if a user authorized to edit form, which means editor privileges or above, has added a 'multiple file upload' form field with '*' acceptable file types.
