Summary
The NEX-Forms – Ultimate Forms Plugin for WordPress plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 9.2.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to enumerate sequential report IDs and download complete form submission data — including names, email addresses, phone numbers, postal addresses, payment details, and uploaded file paths — for any saved report on the site.
