Summary
OpenEMR before 8.3.0 contains a missing authorization vulnerability in the classic document controller that allows low-privilege authenticated users to recategorize other patients' documents. Attackers can invoke move_action_process to move a document into a patients|demo category, then retrieve it with an empty patient_id to exfiltrate PHI and tamper with charts.

Questions about CVE-2026-124486
Is CVE-2026-124486 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 low-privilege user can recategorize other patients' documents into a readable category, then retrieve those documents. This discloses protected health information across patients and lets the user alter patient charts.Source: vulncheck.com, github.com
Which versions are affected by CVE-2026-124486?
openemr: before 8.3.0.Source: cve.now feed data
Am I affected, and how do I check?
The flaw is in OpenEMR versions before 8.3.0. It applies where the classic document controller (controller=document) is reachable and has no base ACL gate, because the controller is missing from CONTROLLER_ACL_MAP. To check, compare the installed OpenEMR version against 8.3.0.Source: vulncheck.com, github.com
How do I fix CVE-2026-124486?
Upgrade OpenEMR to 8.3.0, which is the fixed version listed for this vulnerability.Source: vulncheck.com, github.com
