Telegram Bot & Channel <= 3.8.2 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The Telegram Bot & Channel plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.8.2. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
