CVE-2026-124450: OpenEMR fax/sms module broken access control and path traversal

CVE-2026-124450 · Severity: critical · CVSS 9.9 · Published 2026-11-08

OpenEMR is an open-source electronic health record system that manages patient data and medical records. A flaw in its fax/sms module allows authenticated low-privilege users to read sensitive files like database configuration and write arbitrary files to the server, potentially leading to remote code execution and complete compromise of patient records.

Technical details

The disposeDocument action in the RingCentral and SignalWire fax/sms clients takes an unvalidated file_path parameter without proper authentication or path containment checks. Authenticated users with only the patients/demo ACL (most clinical and clerical roles) can exploit path traversal to read arbitrary files via file_get_contents() or write arbitrary files via file_put_contents() as the web user. This enables attackers to extract database credentials from sqlconf.php and achieve remote code execution.
