## Description

The NEX-Forms – Ultimate Forms Plugin for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'page' parameter of form submissions in all versions up to, and including, 9.3.3 due to insufficient input sanitization and output escaping when the submitted page value is rendered in the admin form entries table. This makes it possible for unauthenticated attackers to inject attributes into the entries table markup that execute arbitrary web scripts when an administrator views and interacts with the form entries.
