Recommended action

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。在 8.3.0 版本之前，中的分支会接受由调用方提供的患者标识符（pid），但未实施患者级别或召回工作流的授权检查。因此，任何低权限的已认证用户若知晓或能枚举出患者标识符，即可获取该患者的详细信息、联系字段、HIPAA 通知偏好、近期预约记录以及现有召回信息。此问题已在 8.3.0 版本中修复。

Vulnerability Title

OpenEMR: Arbitrary Patient Recall and Contact Detail Read

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, the new_recall branch of interface/main/messages/save.php accepts a caller-supplied pid without enforcing patient-level or recall-workflow authorization. A low-privilege authenticated user who knows or enumerates a patient identifier can retrieve patient details, contact fields, HIPAA notification preferences, recent appointment information, and existing recall information. This issue is fixed in version 8.3.0.
