Official description
The Checkout Files Upload for WooCommerce WordPress plugin before 2.4.0 does not validate uploaded file types when its accepted file types setting is left empty, which it documents as the way to accept all files, allowing unauthenticated users to upload arbitrary files, including PHP files that lead to remote code execution on servers that execute PHP from the uploads directory.
