Advisory

Source description from Wordfence Intelligence.

The Slimstat Analytics plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.8.3. This is due to missing or incorrect nonce validation on the update_settings function. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute in a victim's browser via forged request granted they can trick a site administrator into performing an action such as clicking on a link.
