Technical description
The Katalogportal PDF Sync plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.0.0. The katalogportal_popup_shortcode() function is registered as an AJAX handler via wp_ajax_katalogportal_shortcodePrinter but lacks any capability check (current_user_can()) or nonce verification. This allows any authenticated user, including Subscribers, to call the endpoint and retrieve a list of all synchronized PDF attachments (including those attached to private or draft posts) along with their titles, actual filenames, and the katalogportal_userid configuration value. The WP_Query uses post_status => 'any' which returns attachments regardless of the parent post's visibility status.
