CVE-2026-124488 · Severity: high · CVSS 8.1 · Published 2026-11-08

OpenEMR is a medical records system used by healthcare providers to manage patient information and clinical notes. An authenticated clinician without permission to access high-sensitivity patient encounters can bypass access controls to read and modify restricted clinical notes and care plans, compromising the confidentiality and integrity of sensitive medical records. This affects clinicians who should be blocked from viewing certain patients' information but can still tamper with those records through direct form submission.

## Technical details

An authenticated authorization bypass in OpenEMR's load_form.php and form save handlers (clinical_notes/save.php, care_plan/save.php) fails to enforce encounter sensitivity checks that are correctly enforced in the normal encounter UI. An attacker with clinician-level access but lacking the sensitivities|high permission can directly request high-sensitivity form loaders, obtain form content and valid CSRF tokens, and submit those forms to modify restricted records. The vulnerability requires valid OpenEMR credentials and knowledge of a high-sensitivity encounter.
