Pulsating Chat Button < 1.4.2 - Stored XSS via CSRF

Description

The plugin is vulnerable to Cross-Site Request Forgery due to missing or incorrect nonce validation on the amin_chat_button_settings_page() function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
