Until a fix is available, restrict access to pages hosting frontend submission forms or disable the MB Frontend Submission extension if possible. Monitor for updates from the Meta Box vendor and apply official patches once released.
Description
Meta Box AIO plugin for WordPress versions up to and including 3.8.0 contains a missing authorization vulnerability in the MB Frontend Submission extension. This flaw allows unauthenticated attackers to delete arbitrary posts and pages by exploiting the mbfs_delete action routing without proper capability or ownership checks. The nonce verification intended to protect against such actions is bypassable due to being gated behind an AJAX check that does not apply to template_redirect requests. This vulnerability has a critical severity with a CVSS score of 9.1.
