Bulk NoIndex & NoFollow Toolkit < 1.51 - Missing Authorization

Description

The Bulk NoIndex & NoFollow Toolkit plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the update_page_callback() and update_page_bulk_callback() functions called via AJAX actions in versions up to, and including, 1.5. This makes it possible for authenticated attackers, with subscriber-level access and above, to update post and page's noindex and nofollow statuses.
