Vulnerability from fkie_nvd - Published: 2026-03-19 21:17 - Updated: 2026-03-20 15:05
Severity ?
5.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N
Summary
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.2, an authorization bypass in the optional FaxSMS module (`oe-module-faxsms`) allows any authenticated OpenEMR user to invoke controller methods — including `getNotificationLog()`, which returns patient appointment data (PHI) — regardless of whether they hold the required ACL permissions. The `AppDispatch` constructor dispatches user-controlled actions and exits the process before any calling code can enforce ACL checks. Version 8.0.0.2 fixes the issue.
