Accepted Answer

What exactly is the vulnerability in the News & Blog Designer Pack plugin?

The vulnerability is a critical remote code execution flaw impacting versions up to and including 3.4.1 of the News & Blog Designer Pack plugin. By sending specially crafted requests to the bdp_get_more_post AJAX hook, unauthenticated attackers can achieve arbitrary PHP code execution on vulnerable WordPress sites. This is made possible because the plugin improperly extracts data from POST requests and passes it unsafely to include() statements. So by exploiting this, attackers could run malicious PHP code and takeover sites.
