## Description

The Essential Real Estate plugin for WordPress is vulnerable to arbitrary attachment deletion via the front-end property form in all versions up to, and including, 5.3.4, due to missing ownership validation of the attachment IDs submitted in 'property_image_ids' and 'property_attachment_ids' and of the attachments removed by the remove_property_attachment_ajax() and delete_property_attachments() functions. This makes it possible for authenticated attackers, with ERE Customer-level access and above, to add other users' media attachments to their own property and then delete them, removing arbitrary media from the site's library.
