Description

The Social Media Share Buttons & Social Sharing Icons plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.8.5.

This makes it possible for unauthenticated attackers to invoke those actions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
