OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, in , the patient id used for the page is taken from the request ( and ) instead of being fixed to the authenticated portal user. The portal session already has a valid for the logged-in patient. Overwriting it with user-supplied values and using it without authorization allows a portal user to view and interact with another patient's demographics, invoices, and payment history—horizontal privilege escalation and IDOR. Version 8.0.0 contains a fix for the issue.
