Description
The Multi Uploader for Gravity Forms WordPress plugin up to version 1.1.8 contains a missing authorization vulnerability that allows unauthenticated attackers to delete arbitrary media attachments. This occurs because the deletion function lacks proper capability checks and exposes a nonce on public pages, enabling permanent media library destruction.
