CVE-2026-76614
MediumCVSS 4.3Summary
OpenEMR before version 8.3.0 contains a path traversal vulnerability in the EDI archive restore function. The archrestore_sel parameter is passed without sanitization, and differing response messages leak whether the target path exists. An authenticated user with EOB Data Entry permissions can probe arbitrary filesystem paths.
Risk Assessment
An attacker can determine the existence of files and directories on the server, which may aid further attacks such as data exfiltration or privilege escalation.
Recommendation
Upgrade OpenEMR to version 8.3.0 or later, which includes a fix for this vulnerability.
Original NVD description (English source)
OpenEMR before 8.3.0 contains a path traversal vulnerability in the EDI archive restore function. The archrestore_sel POST parameter is passed to the archive restore handler without sanitization for path traversal sequences. The handler checks whether the supplied path exists on the filesystem, and the differing response messages leak whether the target path exists. An authenticated user with EOB Data Entry permissions can probe arbitrary filesystem paths on the server to determine file existence.
