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.
