Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

InvoicePlane 是一款自托管的开源应用，用于管理发票、客户和支付。在 1.7.2 版本之前，InvoicePlane 在其删除方法（包括 Payments::delete()、Recurring::delete() 和 User_clients::delete()）中未调用 ensure_valid_post_request()。尽管这些路由要求使用 POST 请求，但应用并未验证请求的 CSRF 令牌。攻击者可以利用已认证管理员的浏览器提交跨站请求（CSRF），从而删除财务记录及其他应用程序数据。该问题

Vulnerability Title
InvoicePlane: Missing CSRF Token Validation on Multiple Delete Endpoints
Source: CVE Program / CVE List V5
Vulnerability Description
InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. Prior to 1.7.2, InvoicePlane omits ensure_valid_post_request() from delete methods including Payments::delete(), Recurring::delete(), and User_clients::delete(). Although the routes require POST, they do not validate the request's CSRF token. An attacker can submit a cross-origin form through an authenticated administrator's browser to delete financial records and other application data. This issue is fixed in version 1.7.2.
