## Description

The rocket-font plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's settings (such as the font color, font size and class/ID selector list options) in all versions up to, and including, 1.2.3 due to insufficient input sanitization and output escaping on the settings page. Combined with the unprotected settings update handler, this makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator accesses the plugin's settings page.
