Security Vulnerabilities
Pillow is a Python imaging library. In versions through 12.3.0, the libtiff TIFF encoder can pass arguments to TIFFSetField() that do not match libtiff’s definition of the corresponding tag. When an application saves attacker-controlled image metadata through this encoder, crafted tag values can cause invalid memory reads, copying process memory into the encoded output or crashing the process. Applications that return the encoded output to an attacker can disclose that memory. The issue is reachable when re-saving compressed TIFF images and through certain conversions that preserve EXIF metadata into compressed TIFF output. This vulnerability is fixed in version 13.0.0.

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 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 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 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 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 is a free and open source electronic health records and medical practice management application. From 6.0.0 until 8.3.0, interface/globals.php uses the unauthenticated authUser login parameter to populate temp_authuserid and load that account's user_settings before authentication succeeds. Existing usernames can therefore cause an additional database query and may apply visible customized settings, while nonexistent usernames skip that behavior. A remote unauthenticated actor can use timing or page differences to enumerate valid accounts for later credential attacks. This issue is fixed in version 8.3.0.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, interface/forms/transfer_summary/new.php and interface/forms/functional_cognitive_status/new.php render stored transfer_to, code, and codetext values with text(), which uses ENT_NOQUOTES, inside double-quoted HTML value attributes. An authenticated clinical user can store a value containing a double quote that escapes the attribute and injects event-handler markup when another clinician opens the form. Successful exploitation can expose session data and protected health information or permit patient-record actions in the victim's session. This issue is fixed in version 8.3.0.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, interface/patient_file/pos_checkout_ippf.php performs state-changing void, voidall, and regen operations through GET requests without CSRF token validation. The form_checksum integrity check is conditional and is skipped when the parameter is omitted, allowing a cross-site request to force an authenticated billing user to void checkouts or regenerate invoice counters. The resulting changes can alter ledger state, financial reporting, and audit records. This issue is fixed in version 8.3.0.

OpenEMR 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.
