CVE-2026-41258— OpenMRS: Stored Velocity SSTI to RCE via ConceptReferenceRange

Quick assessment

Affected
openmrs openmrs-core
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenMRS是美国OpenMRS公司的一套开源的电子病历系统。 OpenMRS 2.7.0至2.7.9之前版本和2.8.6之前版本存在代码注入漏洞，该漏洞源于ConceptReferenceRangeUtility.evaluateCriteria方法将数据库存储的条件字符串作为Apache Velocity模板评估而未进行沙箱配置，可能导致具有Manage Concepts权限的用户存储恶意Velocity模板表达式并在验证观察时自动执行。

Vulnerability Title
OpenMRS: Stored Velocity SSTI to RCE via ConceptReferenceRange
Source: CVE Program / CVE List V5
Vulnerability Description
OpenMRS is an open source electronic medical record system platform. From 2.7.0 to before 2.7.9 and 2.8.6, the ConceptReferenceRangeUtility.evaluateCriteria() method in OpenMRS Core evaluates database-stored criteria strings as Apache Velocity templates without any sandbox configuration. The VelocityEngine is initialized with only logging properties and noSecureUberspector, leaving the default UberspectImpl in place, which allows unrestricted Java reflection through template expressions. A user with the Manage Concepts privilege can store a malicious Velocity template expression in a concept's reference range criteria field. This payload is then executed automatically whenever a user or API call validates an observation against the affected concept. The Velocity context exposes $patient (the Person / Patient object), $obs (the Obs object), and $fn (the ConceptReferenceRangeUtility instance with access to the full OpenMRS service layer). This vulnerability is fixed in 2.7.9 and 2.8.6.
