Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
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程序，用于管理发票、客户和支付。在版本 1.7.2 之前，InvoicePlane 会存储由管理员控制的 值，但并未对该值进行验证，未将其与允许的自定义字段表名称进行比对。随后，在 函数中，该存储的值被拼接进 SQL 查询的 表名和 列标识符位置。因此，当打开自定义字段编辑表单时，会触发一次二级 SQL 注入。攻击者可以利用此漏洞查询任意 schema 的数据，并可能导致应用程序出错或服务中断（拒绝服务）。该问题已在版本 1.7.2 中得到修复。

Vulnerability Title
InvoicePlane: Second-order SQL injection through the unvalidated custom_field_table field in the Custom Fields module
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 stores an administrator-controlled custom_field_table value without validating it against the allowed custom-field table names. Mdl_custom_fields::used() later concatenates that stored value into the FROM table and WHERE column identifier positions, so opening the custom-field edit form executes a second-order SQL injection. The injection can query arbitrary schema data and can cause application errors or denial of service. This issue is fixed in version 1.7.2.
