The PeepSo Core: File Uploads plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.4.6.0 via the file_download REST API endpoint due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to download files uploaded by others users and expose potentially sensitive information.
