Technical description

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, library/classes/Controller.class.php allows explicit controller.php dispatch to controllers missing from CONTROLLER_ACL_MAP, and checkControllerAcl() returns without enforcing any permission for those entries. A low-privilege authenticated user can invoke C_X12Partner::edit_action_process() to create or alter insurance-routing hosts and credentials, or invoke C_PatientFinder::find_action_process() to enumerate patient names, dates of birth, and identifiers. The shared fail-open dispatcher root cause also exposes other administrative controllers that were intended to be reached through ACL-gated Practice Settings routes. This issue is fixed in version 8.3.0.

——0OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, library/ajax/set_pt.php allows any authenticated user to set an arbitrary patient identifier in the active session without an ACL check, and interface/patient_file/download_template.php trusts that session value while enforcing only CSRF validation. A low-privilege user can select another patient and download a rendered document template containing the patient's demographics, encounter information, allergies, medications, and problem list despite lacking patients/docs access. This issue is fixed in version 8.3.0.4h CVE-2026-1041386.5 MED

——0OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, custom/ajax_download.php, custom/download_qrda.php, custom/export_qrda_xml.php, and custom/qrda_download.php validate CSRF but do not enforce the patients/med ACL used by the canonical CQM report page. The endpoints also accept an unscoped report_id, allowing a low-privilege authenticated user to reach report generation and download logic for other reports. In a clinic with generated CQM reports, this can expose QRDA Category One and Category Three clinical documents for patients in a measure. This issue is fixed in version 8.3.0.4h CVE-2026-1041356.5 MED

——0OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, library/ajax/payment_ajax.php validates a CSRF token but performs no AclMain authorization check before executing a wildcard search of patient_data. Any authenticated user, including a non-clinical role, can enumerate patient identifiers, full names, and dates of birth through the set_patient branch. This issue is fixed in version 8.3.0.4h CVE-2026-1041346.5 MED

——0OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, the search_persons action in library/ajax/person_search_ajax.php validates CSRF but does not perform an AclMain authorization check before searching the person and patient_data tables. A low-privilege authenticated user can iterate name prefixes and receive patient first and last names, dates of birth, gender, phone numbers, and email addresses in JSON responses. This issue is fixed in version 8.3.0.4h CVE-2026-1041337.1 HIG

——0OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, interface/modules/custom_modules/oe-module-dorn/public/compendium_install.php checks authentication and CSRF but does not require the admin/users ACL enforced by sibling DORN administration scripts. When the DORN module is enabled, a low-privilege authenticated user can supply a labGuid that causes LabCompendiumInstall::uninstall() to delete detail and result procedure types and deactivate order types before the reinstall step. The action can corrupt lab-ordering configuration and require an administrator to restore the compendium. This issue is fixed in version 8.3.0.4h CVE-2026-1039395.4 MED

——0OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, interface/modules/custom_modules/oe-module-weno/scripts/file_download.php has no ACL or CSRF check and ignores the result of validateAdminCredentials(). When the Weno module is enabled, the default GET path calls PharmacyService::removeWenoPharmacies() before attempting a refetch, allowing any authenticated user to truncate the weno_pharmacy table and allowing a cross-site request to trigger the same operation through a logged-in victim. A failed later download can leave the e-prescribing pharmacy directory empty and unavailable. This issue is fixed in version 8.3.0.4h
