OpenEMR before 8.3.0 contains a path traversal vulnerability in the EDI archive restore function. (CVE-2026-76614)
OpenEMR versions prior to 8.3.0 contain a path traversal vulnerability in the EDI archive restore function. This flaw allows an authenticated user with EOB Data Entry permissions to probe arbitrary filesystem paths on the server by exploiting unsanitized input in the archrestore_sel POST parameter. The vulnerability leaks information about file existence based on differing response messages.
AI Analysis
Technical Summary
OpenEMR before version 8.3.0 has a path traversal vulnerability (CWE-22) in the EDI archive restore function. The archrestore_sel POST parameter is not sanitized for path traversal sequences before being passed to the archive restore handler. The handler verifies if the supplied path exists on the filesystem and returns different responses accordingly, allowing an authenticated user with EOB Data Entry permissions to determine the existence of arbitrary files on the server. This vulnerability has a CVSS 3.1 base score of 4.3, indicating a medium severity level with low impact on confidentiality and no impact on integrity or availability.
Potential Impact
An authenticated user with EOB Data Entry permissions can exploit this vulnerability to perform path traversal attacks that reveal whether arbitrary filesystem paths exist on the server. This information disclosure could aid further attacks but does not directly compromise data integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict EOB Data Entry permissions to trusted users and monitor for suspicious activity related to the EDI archive restore function.
