Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
OpenMRS Core (org.openmrs.api:openmrs-api) versions 2.7.0 to before 2.7.9 and 2.8.0 to before 2.8.6 are vulnerable. A user with the Manage Concepts privilege can store a malicious template expression in a concept's reference range criteria, which then runs whenever an observation is validated, allowing arbitrary code execution on the server and access to patient data. Upgrade to 2.7.9 or 2.8.6. The source lists no workaround beyond restricting the Manage Concepts privilege and auditing stored reference ranges.
