EchelonGraph scoreLOW confidence

This critical-severity CVE scores 10.0 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). 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 version 7.0.4, the disposeDocument() method in EtherFaxActions.php allows authenticated users to read arbitrary files from the server filesystem. Any authenticated user (regardless of privilege level) can exploit this vulnerability to read sensitive files. Version 7.0.4 patches the issue.
