CVE-2026-39931 openemr CVE debrief

Who should care

Administrators and security teams responsible for OpenEMR installations should be aware of this vulnerability and take steps to patch and mitigate potential attacks. They should verify the affected OpenEMR installations, review database access controls, and monitor for suspicious activity. Additionally, they should limit admin or super ACL privileges and implement compensating controls to restrict access to the backup configuration import feature. Security teams should also review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance, and plan vendor-supported updates or mitigations through normal change control where exposure is confirmed. Compensating controls should be reviewed for exposed systems while remediation is scheduled and verified. Relevant monitoring, detection, and logs should be checked for exposed assets that need extra review. Exceptions should be tracked, remediated assets should be retested, and the item should only be closed after evidence is documented. Asset inventory and vulnerability management processes should be updated to reflect this vulnerability and associated risk. Source tracking and monitoring should be implemented to detect potential exploitation attempts. Rollback and change windows should be planned to ensure timely remediation of exposed systems. The OpenEMR community and related security forums should be monitored for additional information and updates on this vulnerability. Security teams should also consider implementing additional security controls, such as web application firewalls and intrusion detection systems, to detect and prevent potential exploitation attempts. Patch management processes should be reviewed to ensure that OpenEMR installations are up-to-date and patched against this vulnerability. The vulnerability management team should review the CVE record and related advisories to determine the affected scope and severity of the vulnerability. They should also review the OpenEMR installation and configuration to determine if additional security controls are needed to mitigate the vulnerability. The security team should also consider conducting a risk assessment,

Technical summary

The OpenEMR backup configuration import feature contains an authenticated SQL injection vulnerability, allowing administrators with admin or super ACL privileges to execute arbitrary DDL and DML statements against the application database. This vulnerability can be exploited by uploading a crafted SQL file at the form_step=202 parameter in backup.php. Attackers can use this vulnerability to extract credential hashes, modify access control tables, inject backdoor accounts, create persistent triggers or stored procedures, and write arbitrary files to the filesystem where MySQL FILE privileges and permissive secure_file_priv settings are configured.

Defensive priority

Administrators should prioritize patching OpenEMR installations to prevent potential SQL injection attacks.

Recommended defensive actions

• Patch OpenEMR installations to prevent potential SQL injection attacks
• Verify and limit admin or super ACL privileges
• Monitor for suspicious database activity
• Implement compensating controls to restrict access to the backup configuration import feature
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The CVE description indicates that OpenEMR through 8.2.0 contains an authenticated SQL injection vulnerability in the backup configuration import feature. However, the source detail is limited, and further verification is needed to confirm the affected scope and vendor remediation. Administrators should verify the affected OpenEMR installations, review database access controls, and monitor for suspicious activity. The vulnerability allows administrators with admin or super ACL privileges to execute arbitrary DDL and DML statements against the application database by uploading a crafted SQL file.
