Summary
The LatePoint plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.3.2. The vulnerability exists because the OsStripeConnectController::create_payment_intent_for_transaction action is registered as a public action (no authentication required) and loads invoices by sequential integer invoice_id without any access_key or ownership verification. This is in contrast to other invoice-related actions (view_by_key, payment_form, summary_before_payment) in OsInvoicesController which properly require a cryptographic UUID access_key. This makes it possible for unauthenticated attackers to enumerate valid invoice IDs via an error message oracle, create unauthorized transaction intent records in the database containing sensitive financial data (invoice_id, order_id, customer_id, charge_amount), and on sites with Stripe Connect configured, the response also leaks Stripe payment_intent_client_secret tokens, transaction_intent_key values, and payment amounts for any invoice.
