## Description

The WP Directory Kit plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.5.9. When a listing is deleted, the deletion routine (Listing_m::delete) passes every ID stored in the listing's 'listing_images' field to wp_delete_attachment() without checking that the ID is an attachment or that the user may delete it. This makes it possible for authenticated attackers, with Listing Admin-level access and above, to delete arbitrary media attachments from the site. Exploitation requires the option that removes listing images on listing deletion to be enabled.
