Description
OpenEMR before 8.4.0 contains an incorrect authorization vulnerability because the prescription REST API routes check the patients.med ACL instead of patients.rx and request no specific permission bit, so read-only Medical/History access passes the check. Authenticated staff users can reuse the UI-exposed APICSRFTOKEN to enumerate prescription UUIDs, forge prescriptions for arbitrary patients, and deactivate existing prescriptions tenant-wide.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
The records we use list no fixed release for CVE-2026-124483. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
