InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2, InvoicePlane exposes Invoices::delete() and Invoices::delete_invoice_tax() as state-changing routes without requiring POST and validating a CSRF token. When an authenticated administrator loads attacker-controlled content that requests an affected route, the application can delete an invoice or invoice tax record. The cross-origin action can remove financial data without the administrator's intent. This issue is fixed in version 1.7.2.
