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

EspoCRM 是一款开源的客户关系管理（CRM）应用程序。在 10.0.3 版本之前，具有邮件模板编辑权限和批量邮件发送权限的用户可以在模板中引用受限记录字段，因为当按用户应用访问控制列表（ACL）功能被禁用时，渲染器会停止对这些字段进行过滤。相同的行为也影响群发邮件的自动回复：即使群发邮件由管理员控制，普通用户只要能够编辑所选的模板，即可引入该漏洞。渲染后的邮件内容可能泄露受限的用户字段。该问题已在 10.0.3 版本中得到修复。

Vulnerability Title
EspoCRM: Mass email template renderer leaks restricted record fields
Source: CVE Program / CVE List V5
Vulnerability Description
EspoCRM is an open source customer relationship management application. Prior to 10.0.3, a user with email-template edit access and mass-email sending access can reference restricted record fields in a template because the renderer stops filtering those fields when per-user ACL application is disabled. The same behavior affects group email auto-replies when a regular user can edit the selected template, even though an administrator controls the group email. Rendered messages can disclose restricted user fields. This issue is fixed in version 10.0.3.
