Custom Twitter Feeds (Tweets Widget) <= 2.2.3 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The Custom Twitter Feeds (Tweets Widget) plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.2.3. 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.
