CVE-2026-104135

OpenEMR: Missing authorization in payment patient-search AJAX leaks patient directory and dates of birth

OpenEMR 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.

OpenEMR: Arbitrary Patient Recall and Contact Detail Read

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, the new_recall branch of interface/main/messages/save.php accepts a caller-supplied pid without enforcing patient-level or recall-workflow authorization. A low-privilege authenticated user who knows or enumerates a patient identifier can retrieve patient details, contact fields, HIPAA notification preferences, recent appointment information, and existing recall information. This issue is fixed in version 8.3.0.

OpenEMR FaxSMS module: insecure staging of decrypted patient documents in webroot

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.2.0, interface/modules/custom_modules/oe-module-faxsms/src/Controller/SignalWireClient.php decrypts a selected patient document with Document::get_data() and SignalWireClient::uploadFileForFax() writes the plaintext bytes under sites/{siteId}/fax. The module returns the resulting public URL to SignalWire, protects it only with a predictable uniqid() filename, and never removes the staged file. An unauthenticated network actor who obtains or guesses the URL can retrieve persistent patient documents even when drive encryption is enabled. This issue is fixed in version 8.2.0.

OpenEMR: Broken Access Control in controller.php Enables Insurance Routing Credential Hijack and PHI Enumeration

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.

OpenEMR: Missing Authorization on Document Template Download Endpoint Allows Any Authenticated User to Read Another Patient's PHI

OpenEMR 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.

OpenEMR: Missing authorization on QRDA Category I/III download endpoints

OpenEMR 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.

OpenEMR: Patient Data Search Without Sufficient ACL

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, the sms_search branch of interface/main/messages/save.php requires an authenticated session but does not enforce patient or feature-level ACLs. A low-privilege user who cannot access patient data through the normal interface can search the MedEx SMS endpoint and receive patient identifiers, names, phone numbers, SMS permission status, and recent message information. This issue is fixed in version 8.3.0.

OpenEMR Before 8.5.0 SQL Injection via form_icd_codes[]

OpenEMR before 8.5.0 contains an authenticated SQL injection vulnerability in the Syndromic Surveillance module that allows users with Clinician-level privileges to read and modify arbitrary database contents by submitting crafted values in the form_icd_codes[] POST parameter to the syndromicsurveillance/index endpoint. Attackers can inject an unquoted numeric IN() clause and UNION DISTINCT SELECT statement using hex-encoded literals to abuse MySQL extractvalue() for error-based exfiltration of bcrypt password hashes and execute stacked queries that reset passwords, resulting in full administrative account takeover.

OpenEMR before 8.4.0 contains an improper authorization vulnerability in the non-patient POST /fhir/DocumentReference/$docref route that allows low-privileged users to generate any patient's CCDA. Attackers with only demographics and documents permissions can supply a victim patient parameter, then download the full-chart CCDA from Patient Documents to exfiltrate clinical data.

OpenEMR before 8.4.0 Improper Authorization via Prescription REST API

OpenEMR before 8.4.0 contains an incorrect authorization vulnerability because the prescription REST API routes check the patients.med ACL instead of patients.rx and request no specific permission bit, so read-only Medical/History access passes the check. Authenticated staff users can reuse the UI-exposed APICSRFTOKEN to enumerate prescription UUIDs, forge prescriptions for arbitrary patients, and deactivate existing prescriptions tenant-wide.

OpenEMR before 8.4.0 contains an arbitrary local file read vulnerability in REST document download, where the controller passes stored uploaded document bytes to Symfony's BinaryFileResponse as a filesystem path instead of returning them as content. Authenticated users with document upload and download access can upload a document containing an absolute pathname, such as the sqlconf.php location, then download it to read server files and recover database credentials.
