Contact Form Multi by BestWebSoft – Multiple Forms Plugin for Single WordPress Website < 1.2.1 - Reflected Cross-Site Scripting

The Updater plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to 1.2.1 due to insufficient input sanitization and output escaping on the 'category' parameter. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute in a victim's browser granted they can trick a victim into performing an action, such as clicking on a link.
