CVE-2026-39931 — OpenEMR Authenticated SQL Injection via backup.php Import Feature

OpenEMR through 8.2.0 contains an authenticated SQL injection vulnerability in the backup configuration import feature that 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 at the form_step=202 parameter in backup.php. Attackers can exploit the unfiltered shell_exec invocation of the mysql command-line client 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.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.6% (30-day exploitation probability)+7
  • Technical severity (high)+6
  • CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Openemr Openemr).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.

What should defenders know first?

CVE-2026-39931 is "OpenEMR Authenticated SQL Injection via backup.php Import Feature", rated High. It affects Openemr (Openemr); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.2 describes technical severity. EPSS 0.64% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
