CVE-2026-33305

MEDIUMPre-NVD 5.45.4—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 88% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
