Authenticated attackers can upload a PHP file named Controller.php, then request interface/esign/index.php with a traversing module parameter to include it and execute arbitrary code.","published":"2026-11-08T14:18:14.823","modified":"2026-11-08T14:18:14.823","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/openemr/openemr/security/advisories/GHSA-p4v7-crwp-qq7q"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openemr-before-8.4.0-remote-code-execution-via-esign-lfi-and-fax-upload"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-08T14:18:14.823"}}
