CVE-2026-124470 · Severity: medium · CVSS 6.5 · Published 2026-11-08

OpenEMR is an electronic health record system used by healthcare organizations to store and manage patient medical data. An authenticated patient using the hospital's online portal can read confidential medical records—including diagnoses, clinical notes, and allergy information—belonging to any other patient in the system by manipulating report parameters. This allows unauthorized access to sensitive healthcare data without requiring special privileges.

## Technical details

A broken object level authorization (BOLA) vulnerability in portal/report/portal_custom_report.php fails to validate that the requesting patient owns the problem list records they are querying. The code extracts a record ID from user-supplied issue_ parameters and queries the lists table without adding a patient ID condition, exposing fields (type, title, comments, diagnosis) for any record. An authenticated portal patient can enumerate sequential record IDs to retrieve all patients' problem lists and IPPF contraceptive records.

## Affected products
