Executive Summary

This vulnerability is an Insecure Direct Object Reference (IDOR) flaw in the Portfolio Filter Gallery WordPress plugin versions 2.0.2 to 2.2.0. It allows users with the Contributor role or higher to permanently delete media attachments, including video thumbnails, belonging to other users such as administrators without proper authorization checks.
