CVE-2026-76614 openemr CVE debrief

Who should care

OpenEMR users and administrators, security teams monitoring for potential filesystem probing, and IT staff responsible for applying patches and managing user permissions should be aware of this vulnerability. They should review and apply the patch from OpenEMR v8.3.0 or later to mitigate this vulnerability. Additionally, they should restrict EOB Data Entry permissions to trusted users and monitor for unusual filesystem access patterns. This vulnerability can be exploited by authenticated users with EOB Data Entry permissions, making it essential for these groups to take action to protect their systems. Security teams should also consider implementing compensating controls for exposed systems while remediation is scheduled and verified. Asset inventory and monitoring can help identify potential exposure and detect exploitation attempts. Rolling back change windows and tracking exceptions can also aid in mitigating this vulnerability. Source tracking can help verify the effectiveness of these measures. By taking these steps, OpenEMR users and administrators can reduce the risk associated with this vulnerability and protect their systems from potential attacks. This requires coordination between IT staff, security teams, and system administrators to ensure that all necessary measures are taken to mitigate this vulnerability effectively. The CVE record and NVD detail provide further information on this vulnerability, and OpenEMR users and administrators should review these resources to better understand the issue and the necessary steps to take to mitigate it. Security teams should also review the official advisory or CVE record to validate affected scope, severity, and vendor guidance. Planning vendor-supported updates or mitigations through normal change control where exposure is confirmed is also essential. Compensating controls for exposed systems, monitoring, detection, and logs for exposed assets that need extra review, and tracking exceptions, retesting remediated assets, and closing the item only after evidence is documented are all crucial steps in mitigating this vulnerability. By following these steps, OpenEMR users and administrators can effectively miti

Technical summary

The OpenEMR EDI archive restore function contains a path traversal vulnerability. The archrestore_sel POST parameter is not sanitized for path traversal sequences, allowing authenticated users with EOB Data Entry permissions to probe arbitrary filesystem paths. This vulnerability can be exploited to determine file existence on the server. The patch is available in OpenEMR v8.3.0 or later. Affected OpenEMR deployments should be reviewed for exposure, and the patch should be applied to mitigate this vulnerability. Compensating controls, such as monitoring and access controls, should be considered for exposed systems.

Defensive priority

Authenticated users with EOB Data Entry permissions can exploit this vulnerability to probe arbitrary filesystem paths.

Recommended defensive actions

• Inventory OpenEMR installations to identify potential exposure.
• Restrict EOB Data Entry permissions to trusted users.
• Monitor for unusual filesystem access patterns.
• Apply the patch from OpenEMR v8.3.0 or later.
• Verify filesystem access controls and validate user input.

Evidence notes

The CVE-2026-76614 record indicates 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. An authenticated user with EOB Data Entry permissions can probe arbitrary filesystem paths on the server to determine file existence.
