Description

The Broken Link Notifier plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.3.0 via the ajax_blinks() function which ultimately calls the check_url_status_code() function. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
