Advisory
Source description from Wordfence Intelligence, credited to James Golovich.
The Simple Download Monitor plugin for WordPress is vulnerable to authorization bypass due to missing capability checks on the 'sdm_tiny_get_post_ids_ajax_call()' and 'sdm_remove_thumbnail_image_ajax_call()' functions in versions up to, and including, 3.2.8. This makes it possible for unauthorized attackers to access otherwise private files and delete thumbnails.
