Description
-----------

_Bulk Delete_ plugin for WordPress suffers from a privilege escalation
vulnerability. Any registered user can exploit the lack of capabilities
checks to perform all administrative tasks provided by the _Bulk Delete_
plugin. Some of these actions, but not all, are:

- `bd_delete_pages_by_status`: deletes all pages by status
- `bd_delete_posts_by_post_type`: deletes all posts by type
- `bd_delete_users_by_meta`: delete all users with a specific pair of
meta name, meta value

Nearly all actions registered by this plugin can be performed from any
user, as long as they passed to a query var named `bd_action` and the
user has a valid account. These actions would normally require
administrative wrights, so we can consider this as a privilege
escalation vulnerability.

PoC

The following script will delete all pages, posts and users from the
infected website.
