Summary

The Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress (versions up to and including 5.7.1) is vulnerable to Insecure Direct Object Reference. A public, unauthenticated AJAX endpoint loads an invoice by a sequential invoice_id without ownership or access-key verification, allowing attackers to enumerate invoices and create or overwrite transaction intents.

Risk Assessment

An unauthenticated attacker can enumerate invoices belonging to arbitrary customers, create unauthorized transaction-intent rows linked to other customers' data, and invalidate intent_keys awaited by legitimate Stripe/Razorpay flows, leading to data exposure and broken payment webhooks.

Recommendation

Update the LatePoint plugin to a version later than 5.7.1; if not possible, restrict access to the latepoint_route_call action and verify that PayPal endpoints enforce access-key and invoice ownership checks.

Original NVD description (English source)

The Appointment Booking Plugin – LatePoint | Calendar & Scheduling for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 5.7.1 via the OsPaypalConnectController::create_order_for_transaction() action registered as a public (unauthenticated) route through wp_ajax_nopriv_latepoint_route_call. The handler loads an OsInvoiceModel by a sequential integer 'invoice_id' with no access-key/UUID or ownership check (the sibling Stripe and Razorpay handlers require a 128-bit access-key UUID via OsInvoicesHelper::get_invoice_by_key), and then calls OsTransactionIntentHelper::create_or_update_transaction_intent() which persists a transaction intent tied to the target invoice's customer_id, order_id and charge_amount and regenerates its intent_key before the PayPal-configured guard is reached. This makes it possible for unauthenticated attackers to enumerate invoices belonging to arbitrary customers, create unauthorized transaction-intent rows linked to another customer's data, and overwrite the intent_key of any in-flight NEW-status transaction intent — invalidating the intent_key that legitimate Stripe/Razorpay flows are waiting on and breaking payment webhooks for those customers.
