Description
The Task Scheduler plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.6.3 via the “Check Website” task. This makes it possible for authenticated attackers, with Administrator-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
