Researcher Dave Jong - Patchstack

Description

Several themes for WordPress are vulnerable to Cross-Site Request Forgery due to missing nonce validation on the activate_plugin() function called via an AJAX action in various versions of the themes. This makes it possible for unauthenticated attackers to activate arbitrary plugins via a forged request, if they can trick an authenticated user into performing an action such as clicking on a link.
