Summary
OpenEMR, an open source electronic health records and medical practice management application, has a flaw in its MedEx SMS search endpoint that lets a logged-in user with low privileges, who otherwise cannot access patient data, retrieve patient identifiers, names, phone numbers, SMS permission status, and recent message information. The attack can be carried out remotely over the network with only low-level login and no user interaction.
Read the original description
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, the sms_search branch of interface/main/messages/save.php requires an authenticated session but does not enforce patient or feature-level ACLs. A low-privilege user who cannot access patient data through the normal interface can search the MedEx SMS endpoint and receive patient identifiers, names, phone numbers, SMS permission status, and recent message information. This issue is fixed in version 8.3.0.

Questions about CVE-2026-104137
Is CVE-2026-104137 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
A logged-in user with low privileges can use the MedEx SMS search endpoint to retrieve patient search results and contact-related data, including patient identifiers, names, phone numbers, SMS permission status and recent message information. This data is normally not visible to that user in the regular interface.Source: github.com
Which versions are affected by CVE-2026-104137?
openemr: before 8.3.0.Source: cve.now feed data
Am I affected, and how do I check?
The issue affects OpenEMR versions before 8.3.0 where the MedEx SMS search endpoint (save.php with go=sms_search) is reachable by an authenticated low-privileged user session. To check, look at the installed OpenEMR version and whether the MedEx SMS search feature is in use.Source: github.com
How do I fix CVE-2026-104137?
Upgrade OpenEMR to version 8.3.0 or later, which is the listed fixed version.Source: github.com
