Authenticated RCE via unsandboxed Velocity template evaluation
Published May 15, 2026 · Updated May 15, 2026
Code injection in OpenMRS Core 2.7.0 through 2.7.8 and 2.8.0 through 2.8.5 allows remote authenticated users to execute Java code. ConceptReferenceRangeUtility.evaluateCriteria() passes database-stored criteria to a default Velocity UberspectImpl without SecureUberspector sandboxing, enabling unrestricted reflection. Manage Concepts privilege is required to persist the expression, which later runs as the Tomcat process during observation validation and can expose patient data.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=>= 2.7.0 < 2.7.9
- Affected versionversion=>= 2.8.0 < 2.8.6
