Authenticated Care Coordination disclosure via missing ACL enforcement

Published Feb 25, 2026 · Updated Feb 25, 2026

Incorrect authorization in OpenEMR before 8.0.0 allows remote authenticated users to read restricted Care Coordination data. The encountermanager endpoint accepts an Accounting-role session and returns module data without enforcing the Care Coordination ACL configured for Administrator access. Any authenticated account that lacks module permission can issue the captured request and read information reserved for authorized users.
