## Description

The Mang Board plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'category1' parameter in all versions up to, and including, 2.4.6, due to insufficient input sanitization and output escaping. On the plugin's admin settings and user list screens, the value is placed unescaped into the onclick attribute of the modify button. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user, such as an administrator, into performing an action such as clicking on a link.
