Technical details

The plugin fails to properly validate authorization when processing invoice data retrieval requests, allowing authenticated subscribers to access arbitrary order invoice metadata by supplying order and invoice identifiers with an invalid nonce. This authorization bypass affects AJAX endpoints that handle invoice data without adequate permission checks, exposing invoice numbers and timestamps across all orders regardless of ownership.
