EspoCRM 是一款开源的客户关系管理（CRM）应用程序。在 9.3.7 版本之前，具有父记录流访问权限的门户用户可以直接通过门户中的备注（Note）API 获取特定备注，并在已知备注标识符的情况下读取内部流备注。虽然“流列表”响应会正确隐藏 字段为 的备注，但针对单个备注的直接访问检查未强制执行该限制，从而导致内部服务人员的内容暴露。该问题已在 9.3.7 版本中修复。

Vulnerability Title
EspoCRM: Portal User ACL Bypass Exposes Internal Stream Notes
Source: CVE Program / CVE List V5
Vulnerability Description
EspoCRM is an open source customer relationship management application. Prior to 9.3.7, a portal user with stream access to a parent record can directly fetch a Note through the portal Note API and read an internal stream note when the note identifier is known. Stream list responses correctly hide notes whose isInternal field is true, but the direct single-Note access check does not enforce that restriction, exposing internal agent content. This issue is fixed in version 9.3.7.
