## Technical details

The vulnerability is classified as an Insecure Direct Object Reference (IDOR) due to missing ownership validation on user-controlled attachment IDs within the plugin's frontend logic. Specifically, the plugin allows users to store and subsequently delete media attachments without verifying if the requesting user is the owner of the referenced ID. An authenticated attacker with subscriber-level permissions or higher can exploit this to permanently delete any media file in the WordPress library, including those uploaded by administrators. The issue is fixed in version 5.2.0.
