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

EspoCRM 是一款开源客户关系管理（CRM）应用程序。在版本 8.1.0 至 9.3.8 期间，由于 GET 实体流附件（streamAttachments）端点的查询路径允许复杂表达式，认证后的非管理员用户可通过提交精心构造的 where 参数来触发漏洞。利用基于布尔条件的盲 SQL 注入，攻击者可提取任意数据库信息，包括当前活跃的管理员会话令牌，从而实现完全权限提升。该问题已在 9.3.8 版本中得到修复。

Vulnerability Title
EspoCRM: Blind SQL injection via streamAttachments where-clause complex expression
Source: CVE Program / CVE List V5
Vulnerability Description
EspoCRM is an open source customer relationship management application. From 8.1.0 until 9.3.8, an authenticated non-administrator can submit a crafted where parameter to the GET entity streamAttachments endpoint because that query path permits complex expressions. Boolean-based blind SQL injection can extract arbitrary database information, including active administrator session tokens, and can enable full privilege escalation. This issue is fixed in version 9.3.8.
