 "title": "Ultra Addons for Contact Form 7 <= 3.5.54 - Unauthenticated Stored Cross-Site Scripting via Form File Uploads",
 "description": "The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via form file uploads in all versions up to, and including, 3.5.54. This is due to insufficient content validation of text-type uploads and the database addon copying uploaded files into the publicly accessible uacf7-uploads directory without a file extension and without any protection against MIME sniffing. This makes it possible for unauthenticated attackers to upload files containing HTML or script that execute in the browser of a user who accesses the stored file, such as an administrator reviewing submissions.",
