OpenEMR 是一款免费且开源的电子健康记录及医疗诊所管理应用程序。在 8.3.0 版本之前， 允许任何已认证用户在未经访问控制列表（ACL）检查的情况下，将任意患者标识符设置到当前活跃会话中；而 则信任该会话值，仅执行跨站请求伪造（CSRF）验证。因此，低权限用户可以选中其他患者，并下载包含该患者人口统计学信息、就诊记录、过敏史、用药情况及问题列表的渲染文档模板，尽管该用户并未拥有“患者/文档”访问权限。此问题已在 8.3.0 版本中修复。

Vulnerability Title
OpenEMR: Missing Authorization on Document Template Download Endpoint Allows Any Authenticated User to Read Another Patient's PHI
Source: CVE Program / CVE List V5
Vulnerability Description
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, library/ajax/set_pt.php allows any authenticated user to set an arbitrary patient identifier in the active session without an ACL check, and interface/patient_file/download_template.php trusts that session value while enforcing only CSRF validation. A low-privilege user can select another patient and download a rendered document template containing the patient's demographics, encounter information, allergies, medications, and problem list despite lacking patients/docs access. This issue is fixed in version 8.3.0.
