Blog2Social: Social Media Auto Post & Scheduler <= 8.6.0 - Authenticated (Subscriber+) Blind Server-Side Request Forgery via post_url

The Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 8.6.0 via the getFullContent() function. This makes it possible for authenticated attackers, with Subscriber-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.
