EspoCRM 是一款开源的客户关系管理（CRM）应用程序。在版本 9.3.7 之前，具有导入范围访问权限的已认证用户可以通过向 POST /api/v1/Import/{id}/exportErrors 发送请求，并使用其他用户的导入标识符，获取包含该导入中行的 CSV 文件的附件标识符。该端点执行了基于范围的权限检查，但未实施由 Import AccessChecker 及其他相关 Import 端点所执行的实体重属关系检查（即对象级所有权校验）。此问题已在 9.3.7 版本中修复。

Vulnerability Title
EspoCRM: IDOR in Import exportErrors Endpoint Leaks CSV Data of Other Users
Source: CVE Program / CVE List V5
Vulnerability Description
EspoCRM is an open source customer relationship management application. Prior to 9.3.7, an authenticated user with Import scope access can send POST /api/v1/Import/{id}/exportErrors with another user's import identifier and retrieve an attachment identifier for a CSV containing rows from that import. The endpoint performs a scope-level check but omits the entity-level ownership check enforced by the Import AccessChecker and sibling Import endpoints. This issue is fixed in version 9.3.7.
