OpenEMR before 8.5.0 contains a missing authorization vulnerability in ccdaservice/ccda_gateway.php that fails to enforce the patients/pat_rep permission, accepting any authenticated core session. Authenticated users without patient-report permission can request the report_ccd_view action to retrieve the selected patient's C-CDA clinical summary, including diagnoses, medications, laboratory results, and identifiers.
